    BMW E65 Borla Performance Exhaust Systems

    We've been big fans of Borla Exhaust for BMWs since we opened our doors in 1993. Borla produces some of the best-sounding, lightest, longest lasting exhausts on the market. These systems are made in the USA with true T-304 stainless steel inside and out and backed with a 1,000,000 mile warranty. Borla puts and emphasis on quality by using stainless steel throughout their piping and muffler bodies (not a mild steel or coated aluminum). This ensures the muffler does not deteriorate from the inside out. Borla designs their exhausts to complement a BMW's understated sportiness, not overpower it. Borla produces each system to have a deep, sporty tone that doesn't offend or intrude on the cabin. So you hear the exhaust when you want to, not all the time. Most Borla BMW exhausts are a true-cat back and bolt or clamp to the original catalytic converter for an easy install. Each system is engineered for the application and refined in their own sound lab - changing pipe sizing, layout, and incorporating mufflers and/or resonators as needed to achieve a sporty yet refined sound. Borla also produces full race exhausts for the committed enthusiast with cat-delete and test pipes.

    E66 745Li Borla start-up
    Borla has developed this sophisticated, unique exhaust for the 2002-2005 745i and 745Li. This system is a true dual cat-back and incorporates a lead muffler that serves both to attenuate sound and balance pressure, similar to the x-pipes used on other racing exhausts. Augmented with two resonators and followed up with a rear muffler assembly, the system exits with two turned down phantom tips at the rear. Among the amazing qualities of the Borla system: this system flows an unheard of 300+cfm more than stock and weighs in at an amazing 21 pounds less. The Li model is longer, requiring an extension pipe (included in every system). Performance, looks, better mileage and the right sound… this is the perfect E65 exhaust upgrade when you want more of that V8 rumble.

    Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty.
