*Please note:Please provide us with your Vin # when ordering. This product is not C.A.R.B. certified (California) nor is it TÜV approved, we would recommend the OEM cats if it is necessary to pass extremely stringent emissions testing or C.A.R.B. certification. We recommend purchasing our FVD Brombacher Software, part # 23674 or part # 53292 as the stock programming may cause fuel enrichment which can damage your investment. If you already have FVD Software, under our Progressive Tuning Program, we will update the software free of charge. We recommend an installation kit under the exhaust / installation kit category
