What's Included

OEM exhaust valve bracket

In process of engineering our OTL 23+ GRC Catback we discovered removing the OEM valve eliminates the pesky CEL that comes up. Our in-house fabricators came up with a bracket that can protect the OEM valve while maintaining a clean aesthetic. Made from corrosion resistant high-grade 304 stainless steel and paired with zinc plated hardware for protection from the elements.

Installing Bracket Correctly

Be sure to make sure bracket is installed correctly. Installing incorrectly can result in loose fitment or a rattling noise.
