    Unlike the given performance stats from Audi official and car reviewers, the A6 has the capacity to go beyond its indicated maximum power. This applies to all A6 models and can be accomplished by simply installing a high performance exhaust system in place of the stock exhaust. In the 177 hp diesel option, a custom exhaust has the capacity to increase horsepower to as high as 200hp. Turbocharged versions of the A6 benefit not just from massive power gains but also a wider power band, meaning you will be able to enjoy more power from the A6 single/twin turbo engines at much lower rpm levels than before when you install a custom exhaust system. For the best in A6 custom exhausts, check out CARiD’s wide offering. It includes customized exhaust systems from leading manufacturers Borla, MagnaFlow, Flowmaster, Gibson, Zunden, Weapon-R, MBRP, RPB and Onki. CARiD stocks different exhaust systems for all A6 models from these brands. Whether you are looking for the right exhaust system for your upgraded 2002 A6 or the newest 2013 A6, you will find it at CARiD.

    Beyond the indicated power gains and performance enhancement, your A6 will develop a new sound, which is more pleasant and richer. On acceleration, the custom A6 exhaust gives a rich growl commonly heard in high performance sports cars. The exhaust blocks all engine vibrations and unwanted noise such that even at high rpm, the car gives a consistent, non-disruptive tone, something the A6 stock exhaust does not offer. Another important benefit an aftermarket A6 exhaust gives is higher mpg. By releasing more power at lower rpm, you will not need to accelerate as often as before to hit maximum power, and you can cover more miles per gallon.

    Perfect Fit!
    After searching for a new muffler system for 6 months without success for my 1997 Audi A6 Quattro wagon, someone referred me to CARiD...thank goodness! This muffler was a perfect fit. I also purchased the resonator pipe which also connected perfectly to the catalytic converter. Super fast shipping too. Had my parts in days. Wonderful company!
