Will this fit my 2004-2006 Wrangler 4.0L?

It is built as a direct fit for the 2004-2006 Jeep Wrangler with the 4.0L engine. Confirm your engine and model year before ordering, since other Wrangler engines use different exhaust layouts.

Does it come with a warranty?

No written warranty is stated for this part. Ask the seller about any return or defect policy before you buy.

Is it stainless steel?

Yes, the assembly is made of stainless steel, which helps it handle high exhaust temperatures and off-road use.

Our take on the Catalytic Converter Exhaust Y-Pipe Kit

This is a direct-fit stainless steel Y-pipe with integrated catalytic converters for the 2004-2006 Jeep Wrangler 4.0L. It bolts in without cutting or welding and includes mounting hardware. It suits owners replacing failed or clogged converters on a TJ who want a bolt-on fix rather than a custom exhaust job. Against OEM replacement parts it is a lower-cost aftermarket option, but it carries no written warranty and is not CARB-certified, so check your state's rules before buying.
