Mercedes M256 GEN1 Downpipe
The RedStar M256 Gen 1 Performance Downpipe for Mercedes-Benz 3.0L inline-six turbo engines is engineered to deliver maximum exhaust flow and measurable performance gains. Featuring a large-bore 3.5-inch U-bend that smoothly transitions to OEM-spec dimensions, this design reduces restriction while maintaining optimal fitment and drivability.
Developed using advanced 3D scanning and precision reverse engineering, the downpipe ensures a perfect, factory-level fit while unlocking improved turbo response, increased power, and a refined yet aggressive exhaust tone.

Available Options:
- OE-style Heat Shielding with ceramic inner liner - signature REDSTAR thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.
