Awhile back I remember there was threads that certain HKS exhausts caused a loss in power. Does anyone know specifically which exhausts have been dynoed to show a loss?

I know gains are hard to come by on the S, but at least we don't want to loose any power with the exhaust change.

 

I'm going pick one not on the list as well, I love my new Comptech. I put it on this week. Easy to install, great fit, excellent sound.

I find a lot of exhausts are too loud. In fact, when I installed my Comptech I thought I was gonna take it off and go back to stock because of the volume. Thing is though, it's louder than stock, but has a great tone so now I don't mind the sound.

Highly recommended after hearing several different S2K exhausts and finding them all too loud for my liking on a daily basis.
