Product Description

BORLA® Performance Industries offers an outstanding stainless steel exhaust system for the popular Nissan 350Z, and the company was one of the first to offer a performance exhaust upgrade for the original Z cars. The BORLA® Cat-BackTM System (PN 140045) is a real dual exhaust system with an H-Pipe and the legendary BORLA® XR-1® Race-Bred Mufflers for increased performance and sound. Independent dyno tests have revealed astounding improvements of 15-20 horsepower and torque. Power values as high as 25+ horsepower and torque have been reported when combined with the BORLA® specially built premium, high-quality T-304 austenitic stainless steel high Headers (PN 17221). Unlike other aftermarket exhausts, which lose power in the mid-range and low-end, BORLA® enhances power throughout the full RPM range. Serious performance aficionados understand that significant power gains are more than just a big figure at top RPM; they are also powerful torque gains across the whole curve. Borla exhaust's unique straight-through, patented designs allow for tremendous flow gains. The flow rate of the Z vehicle increased by 27% over stock! Power is created through flow. Simple as that!

The lightweight high-quality T-304 austenitic stainless steel BORLA® true-dual Z-car system weighs 12 pounds lighter than the standard single exhaust. With big 4" angle cut rolled edge polished T-304 stainless steel tips and the legendary BORLA® growl, the real BORLA® exhaust once again puts the Zoom in the Z vehicle.. Isn‘t it time you stepped up to BORLA®? BORLA® Performance Industries, the original pioneers of high quality, austenitic stainless steel (better than T-409 or aluminized steel) free flow exhaust, employs its patented award-winning technology to deliver quality, sound, performance gains, and improved fuel economy - all with a simple bolt-on installation. All BORLA® street goods come with the well-known BORLA® written million-mile warranty.
