Borla S-Type Cat-Back Exhaust System for 1999-2004 Ford Mustang Cobra 4.6L V8 Supercharged Manual Transmission Rear Wheel Drive 2 Door Coupe (w/Independent Rear Suspension) (140052)

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Ford has raised the performance bar with the 1999-04 Supercharged 390-horsepower Mustang Cobra. And BORLA Performance Industries, chosen by Ford SVT as the factory exhaust on the last Mustang Cobra R, has updated it further with a high tech, custom tuned exhaust. BORLA Engineers massaged and balanced the complete system based on the Ford ECU Strategy that allows the engine to breath free without interrupting the careful balance of on-board engine management. The Cat-Back system (PN 140052) is full dual with 2.5" aerospace grade high-quality T-304 austenitic stainless steel mandrel bends and generates a straight-through performance based exhaust flow that Not only brings the best out of the Cobra Mustang but also gives that extra capacity for additional aftermarket performance upgrades down the road. Make no mistake, this is an aggressive system and proclaims pure power. We also offer a more BORLA traditional system based on the Cobra R system (PN 14858) that is less aggressive but with identical performance gains. 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, performance gains and enhanced fuel economy ' all with an easy bolt-on installation.

Best ever dog toy
Color: Pink
This is such the clever toy and actually I think it makes my pup more clever too. The ball is tough enough to withstand excessive chewing. I really can’t say enough good things about this particular dog toy. This will keep my dogs attention for such a long period of time and you can truly just watch the wheels turning in his head as he figures out how to get the food out would buy again and I probably will just to have a back up.
