Tho this setup might not sound optimal for some, the following is a run down of my exhaust system;
LG4 exhaust manifolds, SLP Y-PIPE, Gutted Cat, 3" exhaust pipe, and Flowmaster muffler w/dual 2 1/2" tail pipes.
The exhaust system mods made a larger @$$ dyno difference than heads and camb!!! Perhaps it's just the sound, but the little 305 really breathes better and runs cooler.
With such minor performance upgrades as heads, cam, and exhaust I am amazed by how well the Camaro sounds and runs?
Thanks again to those of you who steered me in the right direction.
