Description

CTS Turbo B9 S4/S5 3.0T (EA839) cat-delete test pipe is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts – unleash your B9 S4/S5 3.0T potential! Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.
In addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 test pipe will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust crackle on downshift. The sound will be even louder if you already have an aftermarket exhaust system.

To remove the CEL that will occur, proper tuning software must be used. CTS Turbo recommends choosing a High Flow Cat for the sake of our environment! Use of stage 2 software upgrade is strongly recommended. CEL eliminators or oxygen sensor spacers are ineffective with B9 S4/S5 and will not help. For OFF-ROAD use only.
