stingers with the o/r prochamber. for about 9 months now. not tired of it at all.
Quiet Borla/Steeda with MRT H and love it. Get compliments all the time and sounds great at WOT.
My taste is loud performance sound... I had magnapacks and an o/r H on my 98 loved it. My stingers/prochamber sound don't compare IMO. If I had to do all over, I would get a maggie C/b, magnapacks and tips welded in, and a catted H. But that's just me.
Have Borla Stingers + SS Bassani Catted X. Love the sound, nothing like it! Nice and quiet at idle and nice and loud when you get on it
