Borla XR-1's??
 

Hey guys I have a 229/236 Cammed Ls3 with Tsp Lt's, Dr gas X-pipe and two 1 Chambers flowmaster mufflers dumped. I'm trying to quiet the car down some without giving up any flow or changing the sound to much. How do you guys like the Xr-1s how do they sound?

Sounds a little better than the slp lm2 and has 3" diameter all the way through on the 3" model. The Lm2 only had a 2 3/8 inch diameter inside. It didn't really quiet down the exhaust too much over the lm2 but it definately isn't louder.

True Duals? I have a Borla catback on my lt1 not asking about catback. True duals x-pipe two Xr-1's. Ovals
