Hey all...its been sometime since i picked up a catback exhaust about 20 years!I have a 89 GT with the american Thunder kit from flow. I just recently did a whole overhaul new block .30 over and a trick flow top end kit while im at it I figured lets change exhaust, Hpipe and shortys already on it too. So I know it preference but what will sound just nasty really set off the cam. Flowmaster said I have the 40's now and they make a super 44 which is deeper. but what else is out there? MAC sound good? Any ideas would help alot.
