well i have an 84 chevy blazer that had a 305. i put a 350 with stock exhaust. then i cut the cat-back off. had a single-in dual-out flowmaster put on and it sounds pretty good. (little loud, needs headers to give it a deeper rumble) stock pipes, or the stock size should be fine. i wouldnt go too big, like 3", then you would probably come back to the same backpressure problem.
are you running a 305 or 350? |

NOT in 1st or 2nd Gen Camaros they aren't. Long tube headers are the way to go.
And, pipes in the 2.25"-2.5" range will be more than sufficient, unless you have an engine pumping out an excess of 400 h.p. Obviously, the more free flowing the muffler the better, but it's up to your tolerance level for noise. |
