Borla XR-1
Thanks.
Dual 3" is way overkill. 2.5 will flow plenty for your purposes, unless you're planning on pushing in the neighborhood of 500 ponies.
If you're getting 2.5 inch pipes a 3" muffler will work fine, they'll just neck it down for you. I don't know if borla sells a 2.5 or 2.75 inch muffler. Probably not.
