Product Description


With Cobb’s / CARB Anti-Tampering initiative to their dealers, the release of the V400 OTS mapping, and Cobb’s newly revised exhaust products, we are strictly adhering to Cobb Tuning’s CARB EO policy for ANY street driven car. This means no toggle switches can be modified in tuning, such as modified emissions controlled devices. This also means you must adhere to Cobb’s v400 map policy using their new downpipe to not have a CEL. If your car has a delete/defeat emissions device installed or missing emissions equipment that causes a (CEL), as-is this is not something that can be considered for tuning. Other modifications that do not interfere with emissions can be tuned.

With the push of green energy and electric initiative in the world, making vehicles compliant and use compliant Cobb parts for street use with a proper EO number is paramount. Many future-focused companies are working in this direction to keep our industry alive.

If your car is a race car, proof will need to be available (non-op registration/no plates) and sent via email prior for consideration of race only modifications. Details of what is needed can be found here: CLICK HERE
