on my 95 i have mac shorties, full 2 1/2 inch , catless x pipe, spintech prostreets and tail pipes. i love it. my motor is stock and with the prostreets my car -almost- sounds cammed. pretty sweet. loud idle, smooth tone but raspier with acceleration. and for the money (about $150 shipped pair), you cant hardly beat it (imo). very good flowing muffler to boot.
i have heard bassani on a 331 all motor car and it sounded sick. but something to think about, spintechs can be had for much cheaper than buying a new bassani system. course, bassani i hear makes quality stuff too.
one thing to keep in mind if you go with spintech. they are quite a bit narrower than a flow master, so if you run tail pipes the mufflers they will have to be welded in at a angle so the tail pipes line up correctly. any known good muffler shop -should- be able to do this.
i have some footage recorded. maybe i can convert it and post it
