Borla was among the first with a performance exhaust upgrade for the original Z cars. To create this incredible system, we took our popular 140045 system and gave it the more powerful S-Type II sound with no drone inside the vehicle. This Borla Cat-Back System is a True Dual exhaust with a H-Pipe for increased performance and improved sound. Independent dyno tests have shown gains of 15-20 horsepower and torque. Unlike other aftermarket exhaust systems that actually loose 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 straight-through design allows Borla exhaust incredible flow increases. The Z car flow numbers improved 27% over stock! Flow makes power. The Borla True Dual Z-car lightweight high quality T-304 austenitic stainless steel system actually weighs 11 pounds less than the factory single exhaust. Add to this package a great look with large single 4.5 in. round angle-cut rolled edge bright chrome on T-304 stainless steel tips on each tail pipe. This 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 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, sound, performance gains and enhanced fuel economy - all with an easy bolt-on installation.
