Borla Audi Cat Back Exhaust
We are the largest Borla Distributor for VW/Audi applications in the US.
For the A4 enthusiast desiring a deeper, sportscar growl with enhanced throttle response and power output, we highly recommend the Borla exhaust system.
The is a full 2.25" cat-back system which includes a replacement larger 2.25" diameter downpipe. Our testing has shown an average 15hp improvement using this system, due to its larger pipe diameter and low restriction, straight shot mufflers. This is performance you can feel, and quality you can see.
Exhaust tone is deeper than stock and volume is just slightly louder than stock. The A4 Borla system is full stainless steel and comes complete with all installation hardware and Borla's famous Million Mile Warranty.
