Review of the Gravity Performance Cat-back Exhaust System for the Audi S4 B8 & B8.5 Models 

Bob and Phil fit the awesome Gravity Performance Exhaust System to Chris’s daily driver, his Audi S4 and give it a Tarmacsportz road test review.
We found that the fit and finish of the system was as good as OEM, with absolutely no issues fitting it to the car, and once fitted, it made the car sound much more purposeful with a deep, throaty sound. There was minimal drone at 30, 50 and 70mph, with the system only making itself heard during acceleration.
