I don't really have dump's, they don't work for me. I cut the pipe's about 3in past muffler. With 11.1 comp and cam thumping to the tune 625/661 lift and dur @ .050 being 246/259, dump's sandblast the under carriage of car. The fume's are strong though, i am thinking of welding my tail pipes back on.
I have MAC dumps on my 90 and Im not all that impressed. It sounds good at idle but its not that loud. And to me it almost sounds like a truck, but it might be because my stock radiator fan it loud and I hear it the whole time Im driving. I might try a catback of some sort or maybe diff mufflers.
