Borla Catback Twin Tip Exhaust Audi S4 2.7T 00-02

For the S4 enthusiast desiring a deep, sportscar growl with enhanced throttle response and power output, we highly recommend the Borla cat-back exhaust system. Now available with dual 3" rolled edge tips on a single inlet/dual outlet rear muffler, this system cannot be beat in terms of looks, sound, and performance.

Dyno testing has shown an average 7 crank hp improvement using this system, due to its big 3" pipe diameter and low restriction, straight shot mufflers. The S4 Borla system is full stainless steel and comes complete with all installation hardware and Borlas famous Million Mile Warranty!

The stock exhaust piping measures 2.5" in diameter, whereas the Borla uses true 3" piping and 3" inlet/outlet mufflers. Thats nearly a 32% increase in cross sectional area. No wonder this system really lets the boosted 2.7 biturbo motor breathe easy.

All Borla products are made to order. Please allow 1-2 weeks prior to shipment.
