Description<\/h3>\n\n\n\n

Premium M276 test pipe exhaust system for Mercedes W205 C43 C400 C450 E43 E400 E450 SL400 3.0T. High flow design eliminates exhaust restriction, boosts turbo performance and delivers aggressive racing sound.<\/p>\n\n\n\n

Product Description<\/h3>\n\n\n\n

for Mercedes Benz W205 C-Class, E-Class and SL400 3.0T models equipped with M276 turbo engine adopt restrictive factory exhaust pipes. Stock catalytic converters and narrow pipeline structures cause serious exhaust clogging, high back pressure, suppressed turbo spool and weak acceleration performance, while the dull factory sound fails to match the sport positioning of M276 power units.<\/p>\n\n\n\n

Our upgraded M276 exhaust test pipe is professionally developed for Mercedes full-range 3.0T M276 models. Made of high-standard T304 stainless steel with one-piece mandrel bending and precise TIG welding, it features ultra-high temperature resistance and anti-corrosion durability for long-term track and street use. The straight-through high-flow test pipe structure completely removes factory exhaust limitations, maximizes exhaust gas efficiency, significantly improves throttle sensitivity and releases the full power of the 3.0T V6 engine. It produces a pure, aggressive racing exhaust tone without harsh low-frequency resonance. Strictly following W205 OEM mounting standards, it supports plug-and-play bolt-on installation with no cutting or drilling, ideal for performance enthusiasts\u2019 modification.<\/p>\n\n\n\n
