Introducing the Canadian Auto Performance catless downpipe - Version 2 (V2)! 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

Just had the latest and great hi-flow CAP down pipe installed yesterday. If you research (going back years) the benefits of running the highest volume down pipe (such as faster spool response) seem clear. CAP promises faster spool up, and that's what I 100% notice from a stop. My TTE hybrid turbo feel less laggy and definitely quicker off the light. The quality is solid, and the volume increase compared to my previous performance down pipe is obvious. 5 out 5 stars, would buy again or recommend - especially at this price point.

Install went smooth if you know what you’re doing. Everything fits together well! For $400 even without a heat shield I recommend it! And if you want to stay cheap and be safe you can do what I did and heat wrap it yourself!
