Exhaust System?

Hey all,

I was just wondering what people's advice / recommendations would be as I want to upgrade from my stock exhaust.

Engine is stock 1600cc pushing a 72' bus. I want to chase a few more horses (know I won't get alot),and also looking for a deeper note, something that sounds nice.

Does anyone have any ideas?

Cheers

Josh

Wher u at ???

mt gravatt east, Brisbane, Australia, Earth

if u have the ground clearnce availble u cant beat a good ol quiet pack

i got a thunderbird one and love it
its got a nice deep note, quiet under normal driver but a bit of bark if u hit the go pedal hard and gets rid of that wussy, tinny sounding stock note
out of all the headers i got under the house it flows the best across the board but due to ground clearance or lack of its being dumped for a sidewinder

Hey Joel,

nice nice, well the bus is lowered, but nothing crazy, only about 3 inches i think so there is plenty of clearence. Where abouts did you get the thunderbird from and do you know where I could look at one on a website or something? and my engine is by no means performance, just ol' stocker, you don't think it would be over kill?

thanks heaps for your help mate

Josh

it was probably mick motors but ive bought a few zorts over the years so im not 100% sure
vw fumes corrupt the memory

just about every header mob make a quiet pack
i just like the thunderbird one better than empi, bugpack, SS etc
more solid and bigger pipe design
george at classic vw would have them on his website
sorry to lazy to look atm

some food for thought on the subject tho:
for a beetle but quietpacks fit busses as well

but this is mine anyway

haha thats cool. The petrol fumes don't help either hey haha. Yeah I'm pretty keen to stay clear of anything empi, with all the bad wrap i've heard.

Cheers for all your help and time again mate, and i'm fairly sure you own the sexiest bug i have ever seen, most likely the quickest too:P

cheers

no wukkas, thats what these forums are for

geez u need to get to some VW shows then
my bugs a shitheap compared to most

that is true! pfft now now, im sure you are being modest haha. But there is some pretty smicko ones in VWMA on a regular basis hey...

p.s emailed mick motors and they get a shipment of thunderbird 4-1's tomorrow. Probs will chuck on dual quiet packs and get some J pipes... who needs heaterboxes anyways pfft

haha

cheers

Yeh you obviously havent seen my car if you think his is the sexiest and quickest 😂
Even though it is, as he likes to refer to it, "Pov"😬😂
Simon

What, the little model car??? haha just kidding, that is one stoked paint job mate. Real nice. Whats the donk like?

pffft they are pov
they dont even come with the classic vw rear passenger grab straps
havent u seen theyre the only thing that holds herbie together

plus ill leave it to ur imagination on the other purpose theyre good for 😂

requires a willing passenger with small feet tho.....

No comment 😂
Simon

hahahahah. i was trying to think of a good analogy... something to do with paris hilton.. and looks on the outside but dont go inside...or something rude along those lines you know :P?

😂

BTW Carter, I have a single quiet pack as well and the ground clearance really does suck at times. Gets anoying having to leave every driveway or ramp sideways and my car isn't even lowered. The other problem is that mine doesnt give much in the way of manifold heat, so my car rarely idles 🤪
Does make it sound awesome though and you can feel a small gain in performance 👍
Simon

oh cheers mate for the info. yeah my Kombi never idles to great anyways until it warms up a bit. And even though the bus is lowered, im not sure if it would be as low as a beetle haha, but we'll see hey.

Yeah kinda was after a nicer sound and a bit more oomph so thats good to hear 😂

p.s your wheels are sick. they suit perfectttt

cheers again

josh

Yeh, wheels certianly did come up a treat seeing as they were only a carton of crownies 😁
Thanks again Mactaylor 😀
Simon

Ps. You should post up a thread in Members rides of your Kombi. Would like to see some more pictures of it.

heres how a thunderbird quietpack like mine sounds



theres vids of mine on youtube but u cant really hear it to well over all the other noise

sweet as, that sounds pretty decent! and not to be stalkerish, but i have seen a few of ya vids mate haha...

Actually used it to burn one of my mates with a turbo charged saab who said vw's couldn't be fast...

p.s i put some of my pics up in the members section have a look if you got a minute🙂

thats a tidy cross over low light u got there
one of the very few bays that minilights look good on

and vids are on youtube to be watched 😂

I used to run thunderbirds on my S, sometimes with the quietpack from the previous set of thunderbirds, sometimes with the glasspack that came with the final set. Always had a great sound.

I know I'd love a set for my van, but do they even make ones that can go on a type4 motor? Currently my exhaust, post heaterbox, is quite probably the worst exhaust ever conceived.
It starts off with four pipes, which merge into two, then one. The two sides pretty much point at each other. Then there's the muffler pipe. Same diameter as the rest, with a rather sad looking muffler clamped on after that. Has a horrible exhaust sound, sort of like it's running on one cylinder. I can hear all the valve gear ticking away happily, and this obnoxious "BOB-BOB-BOB-BOB" noise coming from the tailpipe, not the nice burble that real extractors have.

True, thats good to hear! that's what I am after hey, just a bit nicer of a note 🙂

you have a type 4 hey?

well mate, go here and have a look: http://www.pertronix.com/prod/ex/thunderbird/default.aspx

i think you will be plesently suprised by the selections haha.

cheers

Josh

Yep. A type4 motor bay camper. I don't know, giving me a link to that page with the PDF of hardcore porn!

To be honest I never even knew that there were small flange T'birds.

I like the look of the one for the type 4 motor. Except the muffler. I can't make out from the pic what sort of flange they are using. If no-one here knows I might shoot off an e-mail to ask.
Because it's going off to the side I know I can't use my old glasspak. Pity.

Well, if someone for some bizarre reason decided to donate to me some turbo gear (as if that'd happen), I think I would go for that exhaust, have it hooking up out opf sight somewhere, maybe the battery bay with battery relocated, have the turbo there, and the out pipe popping out next to where the in pipe came in, and having just a straight pipe sticking out where the original tailpipe would be. No-one would suspect a thing. Hehehe. Well, that is until it was given some serious boot, the turbo spools and the fiery wrath of an unbaffled turbo spreads to declare Armageddon. Or something like that.

Oh yeah Joel. I did anopther assessment on how to fit a supercharger on a type4 motor, and before I got a headache and gave up again, I noted a few things.

It would be easier than I thought previously to fit a different custom machined crankshaft pulley ring. If the hypothetical pulley were done as a grooved belt, and offset a few mm outwards, and a matching pulley for the alternator were made, it would fit in a stock bay with only one other mod, which is a lot worse than I thought.
There is a small fin on the fan shroud which is the only thing really in the way of that idea, Grind it off you say? That's what I would have done. But for the first time ever I noticed that is where the engine number is stamped, which is a bit weird. It is also stamped underneath where an air deflector needs to be removed to see it.

Starting to like the centre shaft idea even more after that. Or a turbo instead. I've got a great setup for forced induction now. It's killing me that I can't do it!

hahaha i love the deception.... love it.. one day i may do the same thing...


i know that vintage VW has A1 sidewinders... which got a pretty good wrap... A1 won best new VW product a few years ago for it...

stainless and tucked away...pretty smicko

if you got the thunderbird extractor you could always get a zorst shop to do up a flange so you can chuck on a fatboy muffler sideways or something haha

I wish I had T'birds on the van. Instead I have an awful exhaust that looks like it was made by someone on work experience out of scrapmetal. Flows about as well too. Ther is one good thing about it though. The metal is thick enough to be welded with an arc welder. I fixed some of the cracks in the 'collector' with it. By its design I'd say when a cylinder on one side fires, it'd be ramming a decent chunk of its gasses down the pipe for the other side. Very unsmooth move.

I'm tempted to buy another chunk of plate and try to make my own adapter flange. That is, one with the bolt pattern of the big T-birds, but has a small hole to accommodate the pipe diameter of the existing exhaust. Lop off the pipe with the angle grinder, weld on the homebrew flange and at least have marginally better flow for the last part of the exhaust. After the 2->1 collector the pipe is really shameful.

Have any pics of the sidewinders?

I said my setup would be great for forced induction because I have a single weber progressive setup on right now, and there is tonnes of engine bay space, even more now that I've removed the spare wheel well. Not a job I would recommend to anyone who values their sanity.

I think with a turbo / supercharger it'd go from 80 to 100 in less than a minute! Haha.

give that a shot, if not just go here http://www.classicveedub.com.au and look up the exhust / muffler section

yeah if you are going draw through you will need a carbon seal on the turbo.. or something like that apparently haha

i dont have a spare wheel in the back either, and i have a 72, so loads of room haha.

money however, i don't have loads of that🙁 haha

Thanks for that.

I don't have money either 🙁
But I can dream, and when things improve a little here I can start saving too. First thing is first though. Getting it a Victorian rego.

good outlook mate. good outlook

I just shaved a few decibels of anguish off the exhaust. Because I have been fiddling around so much in the bay I checked the timing again. It was at only about 4 or 5btdc. Now it's somewhere around 7ish. Would I wouldn't give for a proper strobe that actually works. I have one but it doesn't. So I'm using one of those inline ones with slightly modded ends to fit on the sparkplug, and into the dissy connector. Their light is pretty poor.
It's also the first time I've started it since I bolted on the steel plate where the spare wheel well used to be. Seemed to take a few dB off cabin noise.

Something just occurred to me.
Over the next five weeks I'll be going to DECA to get what I believe to be a Forklift and HR license, and other warehousing certification. In that group of people it is quite likely I might find a helpful person with a MIG. Maybe.

I really want to start driving my van around again. It runs so much better than the Falcon. It'd want to. I've rebuilt the topend three times, and replaced the entire intake system.

hmmm good strobe light will help. my grandad was a mechanic. so he left alot of his bits and bobs including a decent strobe.... they are fairly cheap from like autobarn / supercheap.

i know what your problem is ... its a ford......

hehehe

Yeah, i think my cruddy strobe came from supercheap or repco. The other one I have that doesn't work is a half decent one, but it doesn't work. Been meaning to have a good look at it to figure out what is wrong.

Yeah, It's a Ford. 🙁 It was an emergency purchased car that ended up being a lot more permanent than I'd intended.

Is it weird that I would love to completely silence the exhaust on the van? I love hearing the mechanicals at work. Funny thing is whenever the exhaust ends up in one of its leaky states if I plug up the tip, the engine idles along fine blowing all the gasses silently out the leaks. But of course above idle it'd blast whatever it was out of the way. Usually one of my thongs if that's what I was wearing on my feet.

On the flipside, I love the sound of tuned extractors too. Most OEM exhausts, or badly made ones irritate me greatly. Currently mine sounds like a sick diesel. As much as I wish they had made a variant of their aircooled boxers in diesel, I'm not so hot on having a vehicle that sounds like one when it isn't.

If Rudd comes through with his cheque at the end of the year, I'll probably be using a part of that to get the van on the road. Then we can all go travelling and camping again. Yeah!

tristan this is the type4 verion of my thunderbird



that would be a nice all round exhaust
they have a great note and being equal length 4into1 flow really nicely
would also have the same 3 bolt large flange as the mine up the top
mines way quieter than a stock exhaust under normal driving but hit the go pedal and it has a nice bark

but its being drowned out by good ol weber intake roar and straight cut gears whining
the price we pay to go fast...🙄

swwwiiishhhh.... hey Joel, if you don't mid me asking, where did you get your wheels. they are sweet as. I reckon they would look decent on my bus:P what you reckon?

they;re speedy hyperfangs i got from a guy on another forum im on
on a corolla of all things
altho i have a lot of time for the little AE92s now my exs one we could not kill

those rims are actually off at the moment while my cars play musical rims to keep the boys in blue happy

so bugs currently getting around in BoostR racing lightweights

oh true true. they are awesome! new ones don't look half bad either

p.s looks like you are running over that cat mate...

boostRs wont be staying
i dont overly like them on it anyway
they just hiding oout on the bug till i get some new tyres on 2 of them

will have a set of 18" porshe turbo twists one day.....

true hey.

wow 18's man that will fill out that arch haha... far out...

will look immaculate

nah not really
my bug has the uncanny ability to make 18s look small
the chrome zeptors in the pic up the top are 18s
altho 19s on abug look just stupid
like a hotwheels toy

true hey?? yeah you gotta have a limit... unless of course you want to look like a hotwheels toy... i.e that purple bug in one of my VWMA mags... WRX donk, chopped and dropped... reuben i think his name was... it look sick but haha.... but hotwheels....

pretty sure Reub was running 16s

anyway hmmm.....
LOL

haha yeah yeah. but the car still looked like a hotwheels car... regardless haha...


stoked on that picture.. so yeah exhausts hey...
