Borla with dual 4"
I put on a Borla exhaust system with 4" dual exhausts exiting right behind each rear tire. Supposed to give me an increase in gas mileage but we'll see. The advertised 20hp boost is evident especially on the low end. To me I'm not used to the resonating growl when I start it up, but I'm slowly getting used to it. By the way, I have a 07 Tahoe, don't know if that was the smartest thing to do but oh well. Would like to know what you think of Superchips flashpaq and what kind of filter is best?
