I love my bassani. Mac does sound nice too, but i liked the quality of bassani better.

Depends on what you want. If I want tone, I like the Prochamber a lot, then the Mac cat back like I have for a little quieter (or in my case for 96-98s[:@]), or Borla Stingers for newer cars. Sounds sexy as hell.

Now if I had a lot of power and wanted to let everyone know, I'd love a LT, O/R X, SLP LM I setup. It doesn't get louder than that (until you start losing parts).

Kooks is probably one of the best to go with if you got the money. Here is my little run down list, of course I'm biased tho.

1. Kooks
2. Bassani
3. SLP
4. MAC (quality makes it this low, sounds great tho)

If you're not cheap and get the acutal stainless version, the quality is just fine.

Well, that but it seems that some people have fitment issues, and others don't. Just seems to be a shot in the dark with them about getting something good or something bad.

to answer your hp estimate question, the place that dynoed my car told me that with the bassani full exhuast and the diablo tuner, he could get me near 50 hp. I think that was at the crank but not 100% on it.
