Product Description

BORLA® Performance Industries offers an excellent stainless steel exhaust system for the popular Nissan 350Z. BORLA® was among the first with a bona fide performance exhaust upgrade for the original Z cars. The BORLA® Cat-Back™ System (PN 140045) is a true dual exhaust with the famous BORLA® XR-1® Race-Bred Mufflers. Independent dyno tests have shown incredible gains in the 20+ horsepower range. When complemented with the BORLA® custom fabricated stainless steel high-quality T-304 austenitic stainless steel Headers (PN 17221), power numbers as high as 24-horsepower have been observed. Unlike other aftermarket exhausts that actually lose power in mid-range and low end, BORLA® gains through the entire RPM range. Serious performance enthusiasts understand that true power gains are not simply a big number at max RPM but rather strong torque gains over the full curve.

The famous straight-through, patented designs allow BORLA® exhaust incredible flow increases. The Z car flow numbers improved 27% over stock! Flow makes power. Simple as that! The BORLA® true-dual Z-car lightweight high-quality austenitic stainless steel system actually weighs 12 pounds less than the factory single exhaust. Add to this package a great look with large 4” angle cut rolled edge polished tips and that famous BORLA® growl. Once again, the genuine BORLA® exhaust puts the Zoom in the Z car. Isn‘t it time you stepped up to BORLA? BORLA® Performance Industries, the original pioneers of aerospace-grade high-quality T-304 austenitic stainless steel (superior to T-409 or aluminized steel) free-flow exhaust utilizes its patented award and race-winning technology to deliver quality, sound, performance gains, and enhanced fuel economy – all with an easy bolt-on installation. All BORLA® street products are made in the USA and carry the famous BORLA® written million-mile warranty.
