Borla X-Pipe for 2005-2008 Chevrolet Corvette (C6) 6.0L/6.2L V8 Automatic and Manual Transmission Rear Wheel Drive (RWD) 2-Door Coupe; Convertible. (60089)

Dual exhausts can provide improved scavenging of spent exhaust gases, at the expense of low-end torque. Adding a balance pipe between the two halves of the exhaust system allows both tailpipes to flow gases from any given cylinder, improving scavenging even more. The X-pipe configuration is particularly effective at improving high-end power without compromising bottom-end grunt. It's superiority is at a cost - it's more complex to fabricate than a simple H-pipe system and may be more difficult to fit under some vehicles.

Borla manufactures these exhaust components in its own factory in the USA. Mandrel-bent on CNC-controlled benders, they are guaranteed to the original user on the original vehicle for one million miles of service. High-quality 304 austenitic stainless steel is used throughout, so your Borla exhaust system will never corrode or rust. Other manufacturers, including the car manufacturers fabricate so-called stainless exhaust systems out of less-expensive 400-series steel. Although 400-series steel is superior to ordinary aluminized mild steel, it can still develop ugly surface corrosion and eventually deteriorate. Professional installation is recommended, because of the necessity of working underneath the vehicle.

Features:

• Built to provide long-lasting service
• Made of austenitic stainless steel for long life
• Adds horsepower and torque throughout the rev range

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.
