# Borla 03-08 350Z True Dual Cat-Back Exhaust 2BOXES

Borla(r) Performance Industries offers an incredible stainless steel exhaust system for the popular Nissan 350Z. Borla(r) was among the first with a performance exhaust upgrade for the original Z cars. The 2.25" Borla(r) Cat-Back(tm) System (PN 140045) is a True Dual exhaust with a H-Pipe and the famous Borla(r) XR-1 Race-Bred Mufflers for increased performance and improved sound. Independent dyno tests have shown incredible gains of 15-20 horsepower & torque. Unlike other aftermarket exhaust systems that actually loose power in mid-range and low end, Borla(r) 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(r) exhaust incredible flow increases. The Z car flow numbers improved 27% over stock! Flow makes power. Simple as that! The Borla(r) True Dual Z-car lightweight high quality T-304 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 T-304 stainless steel tips and that famous Borla(r) growl. It delivers the classic S-Type sound with no drone inside the vehicle. Once again, the genuine Borla(r) exhaust puts the Zoom in the Z car. Isn't it time you stepped up to Borla(r)? Borla(r) Performance Industries, the original pioneers of 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(r) street products carry the famous Borla(r) written million-mile warranty.
