Yes I did. Yes, more rasp.
RogerB, good point, but the Borla is barely louder than stock (std 2.5, dunno about SVT), that's why I did it. I probably wouldn't do it again, it doesn't sound terrible, but not as good either. When I added headers, bye bye ear drums! I added an 18" glasspack in there within a week.
Coincidentally, tomorrow I'm putting on a replacement of that section of the Borla kit, that piece was $170. It's an expensive chunk of the kit (muffler, hanger, flange, and 3 bends in the pipe). To avoid resonator/muffler confusion, I'm talking about the first piece, right behind the cat converter.
