CTS Turbo Resonator Delete X-Pipe - Audi B8/B8.5 S4

The CTS Turbo Res Delete X-Pipe pulls the heavy stock resonators and replaces them with an integrated X-pipe that lets the engine sound the way it was meant to. The result is a deeper, throaty exhaust note with that signature supercharger, but refined enough that you’re not fighting drone on the highway.

We laser scanned the factory exhaust section and matched every OEM hanger and mounting point exactly, it fits like it came from the factory.

Built from 304 stainless steel and TIG welded throughout. Lighter than the stock piece, completely reversible.
