Installed behind the rear axle, Borla Touring axle-back exhaust systems
replace the factory rear muffler(s) and exhaust pipe(s). Following the

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.
a mellower tone than their S-Type axle-backs, Borla Touring axle-back
exhaust systems use engine-specific (not universal) mufflers that are
designed, tested, and optimized specifically for a particular year,
make, and model. They use the latest muffler designs to eliminate sound
frequencies that cause harshness, resonance, and drone. In addition to
superior muffler design, improvements in sound and performance are
accomplished by using mandrel-bent tubing and the application of proper
engine-matched tubing diameters. Welded tips are standard on most
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 Touring 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.
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
Touring axle-back exhaust systems.
