The EVO 10 downpipe w/cat is built with 3” 304 Stainless Steel tubing, which passes through a special high flow metallic catalytic converter. All mirror polished for that show look. The downpipe does add a little sound to an stock exhaust and great gain in horsepower.
This replaces the down pipe and the stock cat on your Evo X. Will bolt up to the stock catback or aftermarket.
