Borla® 60558 - Touring™ Stainless Steel Oval Gray Exhaust Muffler Assembly

Lose your stock muffler and get increased power and performance, awesome sound and great looks. The Boomer Wailtail Stainless Steel Oval Race Muffler will improve exhaust flow, helping your engine make 7-10% more horsepower. The Boomer’s patented straight through muffler design reduces restriction and increases exhaust gas velocity, making sure each cylinder is completely evacuated to make room for the incoming charge. This design absorbs the sound waves without disturbing the power waves, in contrast to the chambered mufflers used by most aftermarket companies. Chambered mufflers use partitions or baffles to subdue sound waves, which also creates backpressure and reduces power.

Borla uses austenitic stainless steel in the construction of the Boomer Wailtail muffler, which contains high levels of nickel and chromium, to resist corrosion. This material is harder than the lower grade stainless steel used by the OEM manufacturers, yet is very ductile. Each Borla muffler contains a stainless steel perforated tube wrapped with several layers of stainless steel sound absorbing material and a layer of ceramic sound absorbing, high temperature material, all contained in a fully welded stainless steel shell. Then Borla goes the extra distance; they fully polish the muffler and install a polished 5” round exhaust tip, so you get great looks right out of the box.
