We began four decades ago as a manufacturer of exhaust systems for such \"concours classics\" as Rolls-Royce and Ferrari cars and have evolved into the premier manufacturer of today's performance vehicles for the street, off-road, and racing.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBORLA® is committed to providing world-class exhaust products which surpass the expectations of our customers. To that end, our facility is complete with a state-of-the art test and development center where we are continually improving our manufacturing efficiency and standards. We have pioneered a variety of improvements in the design of performance exhaust systems. Borla currently holds many US patents for innovative exhaust system technology, and the company has won numerous \"Best New Product\" awards in the industry. Every BORLA® Cat-Back™ system, Header and Axle-Back 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. Over 40 years experience and special merge collector technology provide the ultimate in power and endurance.\u003c\/p\u003e\n\u003cp\u003eThe 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 an average increase of 7-10 horsepower and torque when you plant your foot, and improved gas mileage at cruising speeds.\u003c\/p\u003e","published_at":"2020-08-22T16:52:57-07:00","sort_order":"best-selling","template_suffix":"","disjunctive":false,"rules":[{"column":"vendor","relation":"equals","condition":"Borla"}],"published_scope":"global","image":{"created_at":"2020-08-22T16:52:53-07:00","alt":"Borla Exhaust","width":140,"height":140,"src":"\/\/www.hkptuning.com\/cdn\/shop\/collections\/borla.jpg?v=1633570695"}},{"id":436385874133,"handle":"connecting-pipes","updated_at":"2025-04-29T17:49:25-07:00","published_at":"2024-04-06T09:39:10-07:00","sort_order":"best-selling","template_suffix":null,"published_scope":"web","title":"Connecting Pipes","body_html":null},{"id":162528919613,"handle":"midpipe","title":"Midpipes","updated_at":"2025-04-28T16:38:17-07:00","body_html":"\u003cp\u003eThe midpipe is as the name already gives away, the middle section of the muffler and the catalytic converter.

This 2.5" diameter optional mid section is designed to work ONLY with BORLA Axle-Back systems 11981 & 11981BC. Installation REQUIRES cutting the mid section of the stock exhaust behind the catalytic converters and welding the inlet pipes in 60738 to rear of catalytic converters. It features a merge X-Pipe for increased performance and improved sound. The mid section will increase the overall sound volume while maintaining the S-Type tone of 11981 & 11981BC. Combining the 60738 mid section with Axle-Back systems 11981 or 11981BC will create a Cat-Back system. Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
