For custom needs, BORLA offers universal mufflers (also called resonators). These premium muffler upgrades are made from high-quality austenitic stainless steel. Use of these products may require changes to the OEM system or the fabrication of a completely custom exhaust.
Q: I have a 2005 Nissan Titan SE and i wanted to get a Borla XR-1 muffler but i don't if the dimensions on here for the inlet/outlet sizes are inside or outside dimensions? Answer this question
A: Gully- Thank you for your question. The Borla XR-1 Stainless Sportsman Racing Muffler is a 2.5 inch out side diameter inlet and outlet.

BORLA Performance Industries started over 40 years ago, producing exhaust systems for ultra luxury and ultra performance vehicles including Rolls-Royce and Ferrari. From that history, BORLA developed and patented a host of manufacturing techniques that give their stainless steel exhausts the durability and performance that Jeep drivers flock to. BORLA even patented the way the steel is processed for their Cat-Back system, Header and Axle-Back systems. All use premium, high-quality austenitic T-304 stainless steel, which is better than 409 or aluminized steel. The construction of the exhaust systems is entirely welded and produced with mandrel-bent tubing. It's these high-end manufacturing techniques that make BORLA the go-to exhaust for off-road racers all over the world. Shop Borla Now
