T-304 Stainless Steel Cat-Back™ System

Borla Performance Industries has long been the performance exhaust of choice for BMW production race cars, the Z and M-series hot rods. BORLA R&D Engineers have developed a sophisticated, unique exhaust for the 745i & 745Li 4.5L V8 for 2002-05. This system (PN 140130) 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 race machines. Augmented with two secondary mufflers and followed up with a rear muffler assembly, the system exits with two turned down phantom tips at the rear valence driver side. Among the amazing qualities of the BORLA system: With all the extra tubing and mufflers, this system flows an unheard of 300+cfm more than stock and weighs in at an amazing 21 pounds less than stock -- a true testament to BORLA engineering which also accounts for the performance gains. The Li model is longer, requiring an extension pipe (included in every system). Performance, looks, better mileage and the right sound….what’s there not to like!

 

BORLA, the original pioneers of aerospace-grade T-304 stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy — all with an easy bolt-on installation and backed by an unsurpassed written Million-Mile Warranty.

What is a Cat-Back Exhaust?
A cat-back exhaust replaces the exhaust system behind the primary catalytic converter. A cat-back exhaust usually offers a little less performance improvement than does a more comprehensive exhaust upgrade, but eliminating the pipes behind the cat still pays large rewards! A cat-back system also is just as impressive on the outside as a full exhaust and tells the crowd you mean business.

Pros
- Replace restrictive factory muffler
- Enlarge the rear-most pipes
- Reduce the number and severity of bends in the system
- Weight reduction from stock muffler in most cases
- A better looking exhaust tip
- Polished muffler
- Beefy pipes
- Throatier and louder sound to enhance your car overall
