FAQ
Will I need an ECU tune?
A tune is optional but recommended to maximise gains and eliminate any remaining CEL on DBW models.
How loud will it be?
Expect a noticeably louder exhaust note and quicker throttle response; volume depends on your muffler setup.
Does it reuse stock O₂ sensors?
Yes, the primary sensor remains in the header; the secondary sensor threads into the welded spacer on the test pipe.
