Re: Sorry!!
I have the tri-flow on my 94 325i. It is a very high-quality system, with stainless steel welds in addition to being made completely out of stainless steel. When it came to my local indy shop it looked so beautiful that I wanted to buy another one and stick it on the wall!
The dual 3" tips give a good, non-grapefruit shooting look. The sound is loud, but very nice. Certainly not buzzy like the sound of many exhausts on small displacement four-cylinders. Several local shops have remarked that it was the best sounding BMW exhaust they had ever heard. It sets off car alarms in parking ramps. It does drone a bit below 2500 rpm, but most of them do. It is a lot louder than the RSR exhaust on my NSX (which is something I may change next year, along with some headers. So many mods, so little money)
The most cost-effective exhaust mod is to find an M3 exhaust. I have seen some tests that put the Supersprint and AA systems on top in terms of power increase. In any event, an exhaust isn't going to get you a lot of power, unless you put in headers and remove the cat, but you can expect 5-10 hp/ft lbs. at most, probably less.
I think appearance and sound are fairly important in an exhaust, as the difference between the performance gains from one exhaust to the next are not that significant. You want something that won't annoy you on long trips. The tri-flow may be too loud for some, but if you like your music loud it should be fine.
