The CTS Turbo Audi 3.0T Supercharged V6 Testpipe Set is the solution you've been waiting for your Audi 3.0T V6 equipped with a supercharger. The factory cats are notorious for failure when upgrading your power output. Our test-pipes are designed to seamlessly fit in place of your restrictive stock catalysts, which are situated right before your downpipes. Our test pipes feature 2.5" stainless steel piping, and smooth mandrel bends.
Substantial power gains, improved exhaust flow and a more throaty sound are the main benefits of installing our test pipe. Each pipe is mandrel-bent, and TIG welded by hand.
NOTE: proper software tuning is required to avoid Check Engine Light and to ensure correct operation. Contact your local tuner for more details.
