Exhaust System, Rear Section, Stainless Steel, No Mufflers, Chevy, 5.7L, Kit
Borla S-Type axle-back exhaust systems replace the factory rear muffler(s) and exhaust pipe(s) and are installed behind a vehicle's rear axle. Following the same exhaust path and secured using the original hangers and rubber isolators, Borla axle-back (or rear section) performance exhausts are less restrictive than factory exhaust systems and improve the sound level both inside and outside the cabin.
S-Type axle-back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year, make, and model. Improvements in sound and performance are accomplished by using superior muffler designs, mandrel-bent tubing, and the application of proper engine-matched tubing diameters. Welded tips are standard on most systems.
Many vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the rear axle; so most Borla S-Type axle-back installations are completed in less than an hour with no cutting of the factory system. Vehicles that don't have a factory service-point require cutting, so Borla includes easy-to-follow instructions and hardware to complete the installation.
Borla pioneered the use of aircraft-grade 304 stainless steel tubing, a material with a higher content of carbon and nickel that won't rust or corrode, for the automotive exhaust aftermarket … including Borla S-Type axle-back exhaust systems.
