Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.
Axle Back systems are popular performance parts for customers looking for a louder-than-stock rumble while accelerating. Like a Borla Cat Back™ exhaust system, Borla Axle Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. On certain vehicles we offer more than one sound level for the discriminating driver.
Borla Axle Back systems replace the factory rear mufflers and exhaust pipe improving overall sound & performance on your truck, SUV, or car. Welded tips are standard on most systems running gas or diesel fuels.
Borla created and introduced the "Cat Back™" performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding or cutting, and secured using the factory hangar locations. The Borla “Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant.
Borla Cat Back™ systems improve the overall sound level & performance.
Borla exhaust systems are manufactured in the USA and backed by a limited Borla Million Mile Warranty.
