OTL OEM Exhaust Valve Bracket
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 aesthic. Made from corrosion resistant high-grade 304 stainless steel and paired with zinc plated hardware for protection from the elements.
