Borla exhaust - cat back
I'm awaiting receipt of my 2004 S4 - brilliant red, ebony interior, six speed. Its on its way from a dealer in Texas to NJ. Ads for the Borla mention 7 - 14 % horsepower gains and improved gas mileage. Anyone have their exhaust? Are their claims ligit?
Appreciate any feedback,
