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?

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.
