BORLA® Performance Industries once again proves why we’ve led the aftermarket performance exhaust industry for over 40 years. BORLA® has an exalted heritage with Chevrolet performance vehicles. From the C5R LeMans Winning Corvettes to privateers like KTEC, Pratt-Miller, Lingenfelter and Lou Gigliotti who have enhanced BORLA®’s knowledge of both the vehicle dynamics and power-plant engineering.
The C6 is a muscle car with a big, powerful engine and sophisticated sexy chassis. BORLA® has always used the transfer of technology from racing to the street as a tool, and the C6 plays right into that wheelhouse. With an experienced R&D staff, the BORLA® team gave the Chevrolet mark the attention it deserves, rolling out several system options. Airflow management and exhaust engineering is a science with which BORLA® has more experience than anyone in the exhaust aftermarket.
Our Part #140128 is a true dual Cat-Back™ system employing now famous BORLA® “S” Style race-bred 5” diameter straight-through mufflers that feed two 5” round, rolled edge, angle-cut tips on each outlet. Make no mistake, this is an aggressive exhaust, proclaiming loud and clear that 400+ horses are ready to stampede under this hood. #140128 is a full 14 pounds lighter than the stock system, includes the famous BORLA® X-pipe (also sold separately as Part #60089) after the factory cats and flows a full 300cfm more than the factory system which, as most engine builders will confirm, accounts for the significant power improvements. Perhaps more importantly, this flow will also maximize other performance enhancements because each BORLA® exhaust is tuned to get peak output from any aftermarket performance upgrade.
Weight Comparisons: Stock Cat-Back™ Exhaust (w/ h-pipe)...58 Lbs. BORLA®S-Type Cat-Back™ (w/ X-pipe)...44 Lbs.
Axle-Back systems Only: Stock Axle-Back...40 Lbs. BORLA® S-Type Axle-Back...29 Lbs.
We saw a 10-15 hp gain with our S-Type Axle-Back and a few more with our X-pipe. The full S-Type Cat-Back™ system with the X-pipe should consistently get 12-15hp on a stock C6 but can also get 18+ hp depending on the conditions. Please note a number of variables affect the horsepower delta with dynamometers.
In addition to the quad round-tip system, BORLA® also offer both a quad oval-tip system (#140131) and a dual rectangular-tip system (#140133). All three systems shout American V8 here and can’t help but be noticed.
BORLA® Performance Industries, the original pioneers of premium, high quality T-304 austenitic 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.
