youtube has videos of remus exhausts on bikes and mazda 3's and bmws.

for those that dont know, remus mufflers are used on ferraris, which combined with their v8's and v12's make that sweet sound. (resonators have a lot to do with how a exhaust sounds as well. )

ive used a catback on my old BMW and on my jetta i had the muffler only. they sound the best to me on those cars. Sebring are also nice, pretty much the same as remus in every way but ive never used them.
