Cast Stainless Steel Catalytic Converter

The CTS Turbo high-flow catalytic converter is engineered to maximize exhaust flow and deliver significant power gains for your Mercedes-Benz M177 engine. Designed with advanced CAD technology, this component ensures a perfect fit, replacing the restrictive factory catalytic converter. It is constructed from premium CAST T304 stainless steel and features hand TIG welding with back-purging to guarantee years of dependable performance. Beyond enhancing power and performance, these downpipes will transform your vehicle's auditory experience. When paired with the factory exhaust, they produce a louder, deeper growl with a more pronounced exhaust crackle on downshifts and a confident 'punch' during upshifts. The exhaust note becomes even more aggressive with an aftermarket exhaust system. Key product details include 70mm/2.75″ stainless steel pipes, Cast T304 stainless steel construction with TIG welded and back-purged welds, and it replaces the restrictive factory catalytic converter while fitting within OEM heat shields. This offers a great power upgrade with uncompromising performance, an incredible sporty exhaust sound that remains subtle when cruising, and no drone when used with the factory exhaust. This product is compatible with the 2017-2023 Mercedes-Benz E63S AMG (W213) and the 2017-2020 Mercedes-Benz AMG GT 63/63S (X290), both equipped with the M177 engine. Please note that to prevent a Check Engine Light (CEL) from occurring, proper stage 2 tuning software must be used.
