Borla exhaust anybody?

I run a pair of 2 chamber Flowmasters. They don't slow me down. They are as loud as loud gets. I run a set of header collector baffles on the street, to quiet things down. When I "grudge" race I take them out. When I bracket race I run open headers. You'll see a lot of Flowmasters at the track. Just my 2 cents worth.
