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

The stock Y pipe is not required. Only the stock manifolds.

That is true - but, the LT1 will make 260rwhp with the stock Ypipe so no need to spend money to replace it, and then have to restrict the intake to get the HP down. Also, larger dia aftermarket Ypipes typically end up closer to the oil pan than the stock one, dumping exhaust heat into the oil.

For some reason, my stock Y pipe touches the Canton oil pan. Not sure how to fix it other than smashing the crap out of the Y pipe to try to clearance it.
