I've recently puchased a 91 SC 5 speed with a bad motor. Now that I have rebuilt the engine, it's time for exhaust. After scanning the the forums I've noticed a lot of people are running or recommend a 2 1/2" to 3" to 2 1/2" exhaust setup. I was planning on running a 3" from manifolds to mufflers. I've ported and polished, magnafluxed, and port matched the heads with the intent to let this motor breath. Which exhaust setup is better, 2 1/2" to 3" to 2 1/2" or a full 3"? And what about the resonator, use one or not?
