I'm at the final stages of my CMC camaro build. Last thing, other than Vats issue, is the exhaust.
We have to have the stock y-pipe but after that its open.
My question is what are most people doing?
the easiest would be to turn it out by the passenger door but I think that would be too loud on the occasional rider.
I was thinking of going out the back passenger side using a 6" magnaflow race muffler.
Any suggestions would be appreciated.
Thanks Lee

I'm working on this right now on my car (98 Camaro). I have a stock style Y pipe, and I'm still scratching my head about where to go from there. I'm not a fan of turn downs. In the past I have had exhaust fumes find there way back into the car with turn downs, and depending on the muffler, it can be pretty loud in the car. Then there is the issue of heat.
Originally, I picked up a used aftermarket cat back system, but I have a fuel cell, and there is not enough room for the crossover behind the diff.
I've been looking at piecing together a bullet type muffler , then a 90 to a boom tube that will exit just in front of the passenger rear tire, similar to a stock car. Boom tubes are very thin (1 1/2" ) and only 8" wide. Pretty sure I could put this together for just a little more money then a bullet muffler and having a local shop bend pipe over the axle and exit the rear.
Anyone done or seen something like this on a late model F body?

I've been thinking of doing something similar except using a piece of 3" oval tubing. That would weigh less and would be cheaper. I don't think you need a huge boom tube. You'd have to get the exhaust out past the tire to keep from heating the tire.

I wonder if coming out the side is better than dumping before the axle as far as fumes are concerned.

I just bought all the components and plan to install them early next week. I'll let you know how it goes.
Dr Gas sells a boom tube with a muffler built into the interior. Its cheaper then a typical aftermarket cat back.
