Weistec

We are happy to offer a whole new lineup for the W205 C300 owners.


M274 Downpipe
The downpipe was designed with the most sophisticated Computer Aided Design tools to ensure excellent fitment. The downpipe features 3 inch diameter piping and a laser cut precision flange to mate with factory mounting points, giving this system a perfect fit. Our M274 Downpipe features a CNC Machined 304 stainless steel turbine flange to mate with the turbo perfectly using the OEM clamp. The M274 Downpipe connects to the rest of the exhaust using an OEM style adapter for a simple bolt in installation.

• Constructed of low carbon 304 Stainless Steel
• CNC machined 304SS turbine flange
• Laser cut mounting bracket

M274 VTA
The Weistec M274 VTA (Vent to Atmosphere) Adapter is designed and manufactured as a complete and simple bolt on solution for attaining the "blow-off" sound that many people are fond of on turbocharged vehicles. The M274 engine comes equipped with an electronically actuated bypass valve in the turbo compressor cover that recirculates back into the compressor inlet for near silent operation. With the M274 VTA Adapter, there will be no check engine light as the factory valve is still used, and no tuning or ECU calibration is required.


KEY FEATURES:

• 100% Bolt-On Solution
• No Check Engine Light
• Easy 30 Minute Installation
• CNC Machined Aluminum
• Hard Anodized to Military Spec
• Engineered and Manufactured in USA

Will this downpipe fit the GLC300?

How's the sound of the VTA?
Tune only brings 10hp? 15tq? With downpipe? Why so low?
