2.5" SINGLE MUFFLER CATBACK EXHAUST FOR 00-02 2.7L AUDI S4 (B5) BI-TURBO
Upgrading to aftermarket exhaust systems brings a number of benefits and catback/axle-back system is often the first one to go with. It usually comes with a larger pipe diameter over the stock catback and thus does a better job removing restrictions on exhaust flow. No restrictions equals better flow, and better flow equals more horsepower.
This PowerGo lightweight stainless steel catback system features dual 2.5"(64mm) pipes that will produce horsepower gain across entire RPM range. The incorporated single muffler is designed to create agressive sound with deep and throaty tone.
The piping is constructed from premium 16-gauge(1.5mm) austenitic T304 stainless steel for superior durability. It is fully mandrel bent to maintain high flow rate. TIG welded at all joints, it also combines a cracking and corrosion resistant surface and an obstacle free internal wall. The surface is polished to add an extra layer of protection against wearing in various operating environment.
