Hi guys i have a 2.8l v6 in my camaro, it has 135hp stock, i put on a high performance coil, with a MSD cap rotor, and wires... now, how much do think i will gain from the 2.5" magnaflow cat back, no cat, and pacesetter headers?
thank you!

2.5" will be just a bit big. going from factory manifolds, headers + exhaust only, proly +15whp +9wft/lbs . that would be my guess. the 2.8 wont respond as well to mods like a 3x00 will, fyi.

well i need the cat back, because i have nothing after, the cat, which is actually a glass pack... i was younger and dumber... but what you are saying is that practically the headers are not worth it? im just doing it until i can get my v8 ready...

save the money for the V8, dumping money into a 2.8 iron head is pretty wastefull if you aren't going to keep it.
