CTS Turbo B9 Audi RS5 High-Flow CATS

The CTS Turbo B9 Audi RS5 high-flow cats slot in cleanly where the restrictive stock catalytic converter sits, immediately after the turbocharger. Engineered with the latest CAD technology to fit perfectly in place of the factory downpipes, they are built from T304 stainless steel, hand TIG welded and back-purged for lasting reliability. The payoff is substantial power gains, freer exhaust flow, and a throatier sound.
