(140082)\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\u003eEXCEPT ZR1. BORLA Performance Industries Cat-Back system for the celebrated 1986-1991 C4 Corvette equipped with a 5.7L V-8 engine has been engineered to work with either the popular manual transmission or the automatic. The premium, high-quality, T-304 Austenitic stainless steel system is easy to bolt on, is a direct replacement for the much heavier (by some 20lbs.!) stock system. A 3\" diameter front pipe is mounted just after the catalytic converter leading to a Y-pipe, which splits into two 2-1\/2\" pipes exiting on each side of the rear. The muffler and tip assembly use a 10\"x 5\" diameter round muffler on each side of the vehicle, with your choice of a polished rectangular, rolled edge, angle cut tailpipe tip at each split rear exit (part # 140082) ' or a polished round rolled angle cut phantom tip at each split rear exit (part #140051). Tests have shown an exciting 41% increase in flow for dramatic improvement in power or fuel economy. That now famous, aggressive BORLA growl and sexy look proclaim this block may be small, but it means all business ' we guarantee it for a Million-Miles! With race-bred technology that has been transferred from the many successful BORLA race programs, it was no accident that this BORLA system has won several major Corvette exhaust shootouts. Included in this great and storied past are such famous efforts as the C5-R Race Team that has dominated LeMans along with the Bondurant Corvette program at the Bob Bondurant School of High Performance Driving. Only what you would expect from BORLA, the most winning exhaust in racing.\u003c\/p\u003e","brand":"Borla","offers":[{"title":"Default Title","offer_id":41213269049431,"sku":"BDLS_140082","price":1199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/8642\/1591\/files\/140082.jpg?v=1725092227","url":"https:\/\/jmautosports.com\/products\/borla-cat-backtm-exhaust-system-s-type-140082","provider":"JM Auto Racing","version":"1.0","type":"link"}
