Product Details
Universal Heavy Duty Stainless Steel Round Gray Exhaust Muffler by Borla®. Muffler Inlet Diameter: 3". Muffler Outlet Diameter: 3". Muffler Body Length: 24". Muffler Overall Length: 29". Muffler Sound: Mild / Stock. Muffler Configuration: Center - Center. Get increased performance and the aggressive sound of power with this Heavy Duty Stainless Steel Round Muffler. This muffler includes the same technology used in Borla’s high performance street exhaust systems, but for large engine, heavy duty applications. It’s backed by Borla’s million-mile warranty.
Borla engineered the Heavy Duty Stainless Steel Round Muffler to make the most horsepower and torque with the best sound quality. The 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.
The Heavy Duty muffler is for someone that wants their vehicle to have the real sound of performance, with a throaty, aggressive note during acceleration, but without an annoying drone or resonance through the cabin.
Borla uses austenitic stainless steel in the construction of the Heavy Duty 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. Nevertheless, the increased hardness requires special equipment to form and bend. The muffler contains stainless steel perforated tubes 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.
Borla is so confident in the quality of this muffler that it’s guaranteed against defects in materials and workmanship for one million miles.
