Hey, I was wondering if 3 inch fits over the diff in a coupe, or do you have to bring it out just before the back wheel? I have just been given about nine meters worth of stainless 2-
3 meter lengths, I would rather 2inch, how would I go about retaining back pressure? I was thinking if I took it over the diff, and just had cheap bends then this might restrict enough,
or should I go 2 inch then 3, or just forget the 3 and go 2 through, with free flow mufflers and the mother of all tips, as my mate that gave it too me has a heap of 4 inch, also, im
probably getting a bit too excited here, but do you reckon twin tips would work, or would it be getting to close to the filler pipe and the tank, but does this matter too much, as this
would be the cooler running pipe anyways.
sweet, cheers guys.

2 inch with one V8 muffler will allow any A Series to do all the breathing it needs. Sell your stainless to someone with a turbo, Rotisserie or V8 and buy
da bomb tip.

I can tell yuo only 2.5" can just fit under rear of coupe i tried 3" but it hits ecery where even with mandrel bends The first part of my exhust is 3" with single resonator and
3" s type muffler(semi straight through)
