i have 2 1/4 in. pipe on it right now with a dynomax header and muffler kit. i'm wandering what kind of difference it would make changing the pipes to 3" and going with flowmaster mufflers. any input?

Unless you are pumping some serious HP, 2.5 should be able to handle it.

Yup, general consensus for a small block street car is max 2.5. If that's the engine you have, you should probably leave it as is. I noticed a real difference going from stock on my 302 to long tube headers and 2.5-inch exhaust, but you've already got that minus a quarter of an inch.
