CTS TURBO B8 A4 2.0T DUAL EXHAUST (SEDAN/AVANT)

CTS Turbo brings its T304 craftsmanship to the B8/B8.5 A4 2.0T TFSI with a dual exhaust system, hand TIG welded from the finest stainless steel. It is 100% TIG welded from T304 seamless stainless steel and includes installation hardware and stainless steel clamps. Unlike seamed or non-stainless pipes that crack and decay, this cat-back improves turbo spool and peak power, built from 2.5" T304 stainless that bolts directly to the OEM downpipe or the CTS high-flow downpipe. Fitment with other aftermarket downpipes has not been confirmed.
