As your Jeep ages, more is required to keep it on the road. Unfortunately, it is a fact of life that factory components corrode and fail over time. Replace your clogged or rusted out cat with a Flowmaster Direct Fit Catalytic Converter. This easy to install replacement part is constructed from stainless steel, and directly bolts into place. No cutting, drilling, or welding is required. Even though this catalytic converter meets or exceeds all USEPA 49-state requirements, it is not C.A.R.B. compliant, and cannot be shipped to California. Flowmaster proudly makes their Direct Fit Catalytic Converters right here in the USA!
