The CTS catback exhaust for the Audi A4 B8 and B8.5 2.0T TFSI is a dual exhaust system that is hand-welded using the TIG process from the finest T304 stainless steel. Since its inception, CTS Turbo has been producing performance parts for enthusiasts, by enthusiasts, and the ongoing development of the B8 A4 platform is not limited to FMIC kits or turbo kits.
Every CTS B8 A4 exhaust is 100% TIG-welded, constructed from seamless T304 stainless steel and comes complete with fitting hardware and stainless steel clamps. Inferior products are either made without a stainless steel construction or feature welded stainless steel, which can crack and corrode over time. The CTS Turbo B8 A4 2.0T exhaust enhances turbo Spool-up and peak power. The catback is constructed from 2.5-inch T304 stainless steel and connects directly to the OEM Downpipe and the CTS high-flow Downpipe. Compatibility with other aftermarket downpipes has not been confirmed.
The system fits the Audi A4 saloon and Avant 2.0T TFSI, and is suitable for both manual and automatic gearboxes. The Audi twin rear exhaust valance is required for fitting.
