Tuning (stage 2) is required in order to remove the CEL.
CTS Turbo B9 S4/S5 3.0T (EA839) high flow catted downpipe is made to maximise exhaust flow for highest power gains.
Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from cast 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 high flow cat 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. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.
Features:
- 200 cell steel high-flow cat
- Cast stainless steel body
- Incredible sporty exhaust sound, subtle when cruising
- No drone with factory exhaust
- Install hardware included
