    M157 Modular Midpipes, E63 AWD

  • Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following: Learn More

    Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.

    Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

    Fuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.

    Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel/tire size and weight will also impact chassis dyno results

    Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output

    Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.

    Supporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

M157 Modular Midpipes

For those that are looking for improved exhaust note and flow, but do not have the time or the tools needed to install our True Downpipes, Weistec has the M157 Modular Midpipes.  

The M157 Modular Midpipes feature the same brushed stainless steel tig welded midpipes that are included with our M157 True Downpipe systems.  Normally, they would not mate up to the factory downpipes, but also included are a pair of Midpipe adapters.  These adapters bolt to the factory downpipes on one end and have a V-band connection on the other end allowing for a quick bolt on installation that can be performed in as little as 45 minutes!

Modular and Upgradable

The best part? Thanks to the modular design of this product, in the future a pair of M157 True Downpipes can be purchased and installed using the midpipes that are already installed in the vehicle.  This is perfect for anyone that desides they want to further upgrade their car to get the best performance.  No need to buy another complete exhaust package, ending up with excessive left over parts.

Key Features:

  • System includes Midpipe Adapters, Midpipes, and 2 V Band Clamps

  • 100% mandrel bent and TIG welded

  • Constructed of low carbon 304 Stainless Steel

  • Bolt-on installation

  • Improved exhaust note

  • Improved exhaust flow

  • Upgradable to M157 True Downpipes
