exhaust

[toegead93]

Maybe someone can help me find this info because I don't think I've seen it anywhere. Looking at the images I've seen the exhaust system has a stock H-pipe. What size are the two main exhaust pipes?

I read something somewhere that the stock pipes were 3.75"

Unfortunately, i find that dimension very hard to believe. That diameter pipe on a true dual exhaust system is wayyyy oversized for a stock vehicle wiht the power numbers of the Camaro. To get into that size exhaust, you would be well over twice the Camaro's power numbers to get close to that number, probably closer to 3 times possibly more. Alot of 900 range cars are running 3" duals, and by running too large of an exhaust, you would lose velocity and backpressure, and suffer in the torque department.

3 3/4"!?!?!! i dont think so. i think the stock system is 2 1/2"

Every post I have seen reports 2.5" Dual 3.75 would be big diesel territory.
