CTS TURBO B9.5 AUDI A4/A5/Q5 40TFSI/45TFSI TEST PIPE (2021-2025)
Free up your 2021-2025 B9.5 Audi A4/A5/Q5 40TFSI/45TFSI 2.0T's potential with the CTS Turbo race test pipe.
This race downpipe is specific to the B9.5 facelift platform which uses a V-band style connection at the turbocharger, making it a perfect fit for the 40 TFSI and 45 TFSI Hybrid models.
3.5" diameter stainless steel piping is matched perfectly to a billet v-band flange, allowing for optimal flow as exhaust gases transition from the turbocharger to the rest of the exhaust system. Substantial power gains, improved exhaust flow and a more sporty sound are the main benefits from installing the CTS downpipe.
Our friends at Boost Dynamic Tuning created the best Stage 2 file for this Simos 19.7 EA888.4 platform. CTS Turbo + BDT stage 2 combo is the best bang-for-the-buck performance upgrade for B9.5 40TFSI/45TFSI owners. Now available with end-user at-home tuning.
