Supersprint LH/RH Catted Downpipe System for 2000-02 Audi RS4 [B5] 2.7T - 763341 / 763321


Quick Overview

Sku # : Supersprint_Metallic_Cat_Audi_B5_RS4_JY
Specify LH+RH or LH or RH Only

For drivers who love to take their Audi to the tracks and push their vehicle to the limit, a durable and free flowing metallic racing catalytic converter is a MUST--especially those with high horsepower performance applications!  If you're equipped with an ordinary OE ceramic catalytic converter, pushing enormous amounts of power or using your car on the track will melt down and damage your converter quickly.  Every Supersprint racing converter is manufactured to RACING SPECIFICATIONS, utilizing a high heat resistant metallic core.  The reduced cell count from the OE 400 C.P.S.I. to a high-flow 200 C.P.S.I. makes these Supersprint racing converters the MOST free-flowing on the market today!  All components, inside and out, are 100% STAINLESS STEEL, and all tubing is mandrel bent to guarantee the highest flow volume.  Enjoy!

Replaces factory catalytic converter.

  1. Established in 1955, Supersprint develops and handcrafts the best sport car performance exhausts in the business.
  2. Supersprint is the only exhaust manufacturer that individually tests each of its components, from the racing-design headers to the exclusive, high-flow metallic catalytic converters to the rear mufflers, in order to ensure perfect compatibility and peek function, even in conjunction with the OEM exhaust parts.
  3. Supersprint is always among the first manufacturers, and quite often the one and only, in building performance exhausts for the latest sport cars.  Supersprint's proprietary international patents on some of its exclusive headers' merge collectors design, as well as on some silencer designs, had not yet been surpassed by any other manufacturer in business.
  4. Supersprint is the only exhaust manufacturer who offers its tail pipes in a wide variety of styles, with over 100 different shapes and sizes. Supersprint even owns international patents for more than 20 of its special design exhaust tips.  With Supersprint, each and every car tuner has the option to find the exhaust style that suits their cars the best.  The same freedom of choice is left to you...that is, if you decide to go with the Supersprint program.
  5. Thanks to experience coming from the strong, long-term connection between Supersprint and several car manufacturers' factory racing teams, Supersprint is the only exhaust producer that actually designs from scratch, develops their idea, and produces real performance systems, all out of its own knowledge, without copying any one else's projects.
  6. Supersprint is the only company in the exhaust business, who performs more than 1,500 dyno tests yearly, using its own exclusive MAHA 4x4 dynamometer.
  7. Supersprint is the only exhaust producer, who develops and sells only free-flow exhausts, each suited to the car's particular engine type.  The dimensions of the pipes and the inner silencer cores' are carefully determined in each application for the best results.
  8. With more than 45 years of knowledge and Supersprint's worldwide success of exhausts, their systems are the most copied in the business.  Not surprisingly, many of their competitors do not even own a dynamometer for measuring the performance of their products.
  9. All of the Supersprint exhausts are specifically suited to each specific car model, and guarantee an ideal blend of performance increase, reduction in exhaust backpressure, a nice sporty sound and legendary durability.
  10. Supersprint is the only manufacturer guaranteeing that all of its exhausts use premium quality stainless steel, offer a flawless fit into the car, and finally give a sporty, yet not offensively loud, sound.  The authentic "TÜV approval" found on our road legal systems guarantees just that, and this feature is acknowledged worldwide.
