*FREE SHIPPING TO LOWER 48 USA!*

Introducing the Canadian Auto Performance high flow cat downpipe! Newly released for 2024, we have redesigned our V1 downpipe from the ground up to maximize the diameter as well as make it look more aesthetically pleasing! You will not be disappointed with, in our opinion, the best looking and the best flowing downpipe on the market today. 

It's time to increase your B9 Audi S4/S5'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.

• 100% TIG welded & back purged
