You will not be disappointed with, in our opinion, the best looking and the best flowing downpipe on the market today. 

Why Choose Our B9/B9.5 3.0T Downpipe?

It's time to increase your B9/B9.5 Audi SQ5's power, by increasing exhaust flow.

Experience increased horsepower, faster turbo response, and a meaner exhaust note. Easy to install and built to last your car's lifetime.

We have to thank Audi for the design of the OEM cat, compared to the B8/B8.5 S4/S5 platform, replacing cats was a total nightmare on those cars. Although professional install is always recommended, the install time of this downpipe generally only takes around the 2 hour mark.
