Every BORLA Cat-Back™ system, Header and Rear Section is made from austenitic stainless steel (superior to 409 or aluminized steel) employing mandrel-bent tubing, all-welded construction, and is designed for accurate fit and easy installation. Nearly 30 years experience and special merge collector technology provide the ultimate in power and endurance.

The performance advantages of a BORLA are widely recognized. The top engine builders in the racing world rely on BORLA exhaust for maximum performance. In fact, BORLA is at the forefront of the movement toward responsible racing with our full line of patented, award and race-winning racing mufflers that not only maintain a race engine’s power, but in some instances actually add power. This technology is incorporated into BORLA exhaust for the street, providing 7-10% increased horsepower and torque when you plant your foot, and improved gas mileage at cruising speeds. 

BORLA exhaust is built of aircraft-quality austenitic stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Coating techniques, such as aluminizing, can somewhat prolong the life of mild steel, but coatings suffer at the weld points. And, comparing aluminized steel to T-304 stainless steel is like comparing gold-plated metal to solid gold! T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system. Note: Only the flanges are not stainless. In our twenty-year experience, we have found the 3/8"--1/2" flanges are so thick they will never affect the performance or longevity of the system.

BORLA doesn’t stop with unsurpassed technology. We engineer and manufacture all our exhaust products in the USA of aircraft-quality T-304 stainless steel and back our street exhaust with a Million-Mile Warranty.
