CTS Turbo HIGH-FLOW cat set for Mercedes Benz C43 C400 C450 E43 E400 E450 with M276 engine

CTS Turbo high-flow cats maximize exhaust flow for the biggest gains on Mercedes-Benz C43 AMG, C400, C450 AMG, E43 AMG, E400, and E450 models with the M276 engine. Designed with the latest CAD technology to drop in for the restrictive factory cats, they are manufactured from cast T304 stainless steel, hand TIG welded and back-purged for years of reliable service. Beyond freeing up the 3.0 twin-turbo, they add a louder, deeper growl with pronounced crackle on downshift and a confident punch through the gears.
