Show original supplier description

The Weistec M275 Downpipes and Exhaust system is engineered to enhance the performance of M275 AMG powered Mercedes-Benz vehicles. By replacing the restrictive factory downpipes, this system aims to deliver noticeable gains in power, improved throttle response, and a more aggressive exhaust tone. Constructed from durable, low-carbon 304 stainless steel, the components feature 100% mandrel bends and TIG welding for optimal flow and longevity. The 3-inch diameter piping and included Midpipes and X Pipe create a high-flow exhaust pathway while retaining the factory mufflers. Installation is designed as a bolt-on process, utilizing factory turbine clamps and stainless steel brackets for secure fitment. Please note that this product requires ECU tuning to run properly. Additionally, delivery times can be extensive, with an expected wait of approximately 8 weeks. It is also important to be aware that this product may not be emissions compliant, and buyers should verify local laws before installation.
