anybody have sugestions
Drop i a V8
For brands i think anyone will do. Maybe even custom made locally? I prefer flowmaster pipes. The seem to last longer. I really dont know how a inline 6 would sound louder. I have heard some cars done, and it sounds bad. But some were good. I had a 98 grand prix with a 3.1L V6 and it sounded good. Maybe try for 2-1/4 single, or 2" dual pipes and a free flowing muffler and pray for the best. IMO its not going to sound as good as a V8, but you may like it, and thats all that matters. Maybe do a search on youtube for chevy inline 6 exhaust and see if there is some with the sound you like.
