Just as a bit of a warning to those thinking of buying a sidewinder exhaust, there may be some fitment issues.

First issue was that the flange on the muffler was welded at an angle not suitable to my engine fitment (2180) and I had to cut a slot and open up the angle and then have Westi weld it up.

Now that I have fitted the muffler to the car, it is still tight along my inner guard area but my wheels being wide hit the muffler. I may have to go back to Westi and see if he can modify the muffler or make me a new design muffler.

3rd problem - I have rear disc brakes with handbrake fitted on the rear and the flexible line of the caliper is also just touching the muffler (not good).

Now with all this said, different brand may be a straight bolt on fit but I just wanted to let you also know that you may have fitment problems.

P.S. Excuse the dust on the muffler, I have had it sitting here a while

Kev,

How does it look at the back of the beast?

kev is this the A1 sidewinder?

No, and if anyone wants to know where I got it just PM me.

Kev

on roses oval we fitted the muffler laying flat just below RHS tappet cover & on the 70 bug we fitted a skinny muffler between the wheel and inner guard.
And don't worry about not being able to see the stainless steel muffler & pipes because if you drive the car the exhaust pipes go dull brown.

your better off getting a custom made exhaust and muffler that comes off easy to check the tappets etc and get it ceramic coated and it wont go brown and look shitty.

Although I'm never likely to get one this is the sort of info that is needed. My son is finding out the hard way that whenever you change something it can snowball into a myriad of other problems that need sorting out, we're changing the rear suspension and fitting discs and the problems encountered (and one by one sorted out!) are too many to list

I recently got a sidewinder from Wolfsburg Automotive and I'm pretty happy with it. None of the flanges are welded, which means that you're guaranteed to be able to align it, but it does make it a bit more troublesome for leaks as the sealing area is quite small. I had a bit of trouble getting mine to fit but it went on eventually and clears everything. The supplied steel bar to hang the muffler from the #1 cylinder pipe doesn't fit and is useless, but the bloke selling it warned me of that before buying. I replaced it with some sections of used timing belt.

Been there - is also a challenge if you have drain backs from your heads. Yours looks like a different design to any I've seen as the muffler usually lays flat.

Also, heat shield to the valance may be worth considering with your flash paint job. I ended up with a lot of heat behind the valance on my 58 and now have to repaint it...
You can buy good sized sheets of modern honeycomb aluminium exhaust shield on ebay.

be thankful its not like this one too...

exhaust pipes running right next to the pushrod tubes seem ok to anyone else?
looks waaaaaayyy too cosy for my liking.

Good on ya STi, I shield the exhaust from the pushrod tubes to keep the heat transfer to a minimum.......

this is also a Sidewinder

Kev

I think one of the main points is if it has a downturned outlet
This points the sound to the ground

As for the actual muffler, I think it has more to do with the quality and density of the fill rather than the size of the actual muffler
All I know is the one I have is pretty quiet.
Some bloke up at Bathurst made it

they do

The true A1 systems seem to go on alright, this is the second one Ive fitted in the last 3 years with no problems

Doesn't look like that one has any heater boxes though........and no sign of any rear wheels

yep definately no wheels....but still....nice muff

Heat, who needs heat
