Really Hot Mufflers???
My muffler on the back of my bay after running for a little while get really bloody hot, is this a common thing? The car's been dyno tuned and runs
fantastically so it's not running lean, but the heat from the muffler just seems more than it should be. What's other peoples experience with the
heat of mufflers on a bay? With the fan housing and fan just next to the muffler it seems that if it's radiating too much heat it's going to effect
the cooling system a bit, any thoughts?
Note: Its just a standard muffler.
Cheers,
Dustin

Neh, it's exhaust! It's gonna be pretty warm. I know what it's like to kneel back there in the sun on a 40degree day after driving for some time.
Nice! Gotta love her though!
Cheers, Aurel.

Yeh I hear ya, if it was flatter it'd be great for frying eggs! Anybody else got any opinions/experience about the extreme heat from the muffler on a
bus? Do other people's get incredibly hot?
Cheers,
Dustin

I gotta ask this:
How do you define "more than it should be"
What exactly is "should be"??
Exhaust gas temps can reach as high as 1200 or 1300 Deg. F under NORMAL driving conditions. This is warm enough to remove quite a few layers of skin

Relax.

the flame is mostly blue, with a clear center that comes out of the exhaust ports, and the heats gotta go somewhere, no if i remember correctly
clear/white flame is the hottest, cant remember how hot tho, didnt pay that much attention @ school, lesson learnt easy, dont touch it until its sat
and cooled down for prolly @ least 20mins, other wise ya gunna get burnt

Timing or jets
If your timing is too advanced it can make the exhaust hot.
Or if you're engine is too lean it can get hot. I know you said your car isn't running lean but how do you know. If you dyno tuned the car and
jetted it to suit then the jetting combination might not be right for the road or when the engine is hot. Hot engines need more fuel so it could be
lean.
The hot exhaust is probably a good indication to check to see if something isn't right.
Those are my thoughts.

I always ran extractors on my bay but had to go back to a standard exhaust when on a road trip cuz its all i could get a hold of, and i imediately
noticed the heat was held closer to the engine, body and bumper...ended up peeling the paint off the bumper (which is also symptomatic of a shit paint
job). But nonetheless the heat difference was noticable! She ran a little hotter and I didnt like it, so put extractors back on - but that was just my
preference !!

Thanks for the info, I might go and have a chat to the dyno people, see what they think. I'm just assuming that because they tuned it all nice and
proper and it doesn't feel lean that it should be right but.... I'll ask them about the timing too, that could be too advanced.
I would kinda think that they would do the dyno tuning when the engine was at warm running temp but maybe not.
Thanks again for the info, I'll have a look into it.
Cheers,
Dustin

Nice pic with decent breakdown. Is that a different aftermarket heater box or something? The one big exhaust port where the muffler attaches looks
pretty cool, not hugely different though...

it looks like the 411 heater box cause of the exhaust port on the heater box and that it has no alloy fins on the heater box
