question, i have a borla non adjustable cat back, would it be possible to just use one xr-1 muffler, since it is a catback currently, vs two on a true dual set up?

I swapped to XR-1's from Dynomax bullets, they quieted down the car quite a bit...great sound.

Socalspd-Thats exactly what I was looking for, but I have changed directions now lol. I went with a kooks y-pipe to a 4" mufflex. Hoping it will quiten it down some.
