(140135)\u003c\/p\u003e\u003cp\u003eUpgrading 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.\u003c\/p\u003e \u003cp\u003eThe 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.\u003c\/p\u003e \u003cp\u003eBorla 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 \u0026amp; 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 \u0026amp; nickel that won't rust or corrode.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eHorsepower and Torque Increased by 7 – 10%\u003c\/li\u003e \u003cli\u003eIncreased exhaust flow for better performance\u003c\/li\u003e \u003cli\u003eBetter fuel economy at cruising speeds\u003c\/li\u003e \u003cli\u003eThe most aggressive sound of any Borla system\u003c\/li\u003e \u003cli\u003eCustom designed for each application\u003c\/li\u003e \u003cli\u003ePatented straight-through, multi-core muffler design reduces backpressure while absorbing sound waves\u003c\/li\u003e \u003cli\u003eMandrel-bent stainless steel tubes with diameters optimized for reduced restriction while maintaining exhaust gas speed\u003c\/li\u003e \u003cli\u003eMade from the finest austenitic stainless steel for long-lasting durability\u003c\/li\u003e \u003cli\u003eAll welded construction\u003c\/li\u003e \u003cli\u003eIncludes everything required for installation, including detailed instructions\u003c\/li\u003e \u003cli\u003eBacked by the exclusive Borla Million-Mile warranty\u003c\/li\u003e \u003cli\u003eProudly made in the USA more\u003c\/li\u003e \u003c\/ul\u003e\u003cp\u003eFor over 4 decades, BORLA® Exhaust has been the choice of Mustang experts, from the Cobra-R SVT Mustang to the new Ford GT. Major players in the racing industry and leading tuners from Roush, Steeda, Saleen and Ford Racing to the Shelby 427 Cobra have relied on BORLA. And, when the '05 Mustang was first being reviewed, BORLA was already busy designing an awesome Cat-Back system that bolts behind the factory H-pipe, is lighter than the factory system and includes our famous \"S-Type\" mufflers (PN 140135). X-Pipe (PN 60092) may be added to this system.\u003c\/p\u003e \u003cp\u003eBORLA experience and advance engineering have produced a sexy \"S-Type\" exhaust with outstanding flow numbers that generate great power enhancements. These attributes, coupled with an aggressive sound of power and awesome big bright chrome on T-304 stainless steel tip, proclaim this Stang is all business. Airflow management and exhaust engineering is a science with which BORLA has more experience than anyone in the exhaust aftermarket. The performance matches the famous BORLA systems of the past but with a unique muffler and exhaust configuration canceling additional high frequency sound waves.\u003c\/p\u003e \u003cp\u003eDelivering a significant increase in CFM from the factory system which, as most engine builders will confirm, accounts for the dramatic power improvements. Perhaps more importantly, this added flow maximizes performance for other aftermarket enhancements installed on the Mustang because all BORLA exhaust products are tuned for maximum output from any aftermarket performance upgrade.\u003c\/p\u003e \u003cp\u003eTwo Axle-Back system options are also available: an aggressive \"S\"-Type (PN 11750) and a more mellow Touring (PN 11752) - both replace only the over-the-axle pipes, mufflers and tips.\u003c\/p\u003e \u003cp\u003eBORLA's 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.\u003c\/p\u003e \u003cp\u003eBest of all, each system come with the unsurpassed BORLA; written Million-Mile Warranty.\u003c\/p\u003e","brand":"Borla","offers":[{"title":"Default Title","offer_id":41213271736407,"sku":"BDLS_140135","price":1049.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/8642\/1591\/files\/140135.jpg?v=1725092373","url":"https:\/\/jmautosports.com\/products\/borla-cat-backtm-exhaust-system-s-type-140135","provider":"JM Auto Racing","version":"1.0","type":"link"}
