The CTS Turbo Ford Raptor EcoBoost 3.5L High Flow CATS are designed to maximize exhaust flow for the highest power gains. Designed using the latest CAD technology, this part fits perfectly in place of the restrictive factory catalytic converter. Machined from cast T304 stainless steel, hand TIG-welded and refinished to ensure years of reliable performance.

Besides unleashing the power and performance of your 3.5L Twin Turbo, our High Flow CATS will make your vehicle sound like it should. When installed with the factory exhaust, it produces a louder, deeper growl with a much clearer exhaust note. During upshifts, you'll enjoy a confident "pop!" as you shift through all 10 gears. The sound will be even louder if you already have an aftermarket exhaust system.
