Macht Schnell Exhaust Valve Control Module


We are adding more to our performance store all the time! Recently we expanded our KW Suspension section to include almost every BMW performance model available, and now we are proud to introduce the new Macht Schnell Exhaust Valve Control (EVC) Module. This is compatible with the following BMW models:

  • F2x 2-series
  • F3x 3-series + 4-series
  • F8x M3 + M4

Compatible with all exhaust systems (OEM or aftermarket) that retain the factory EVC control, the Macht Schnell Exhaust Valve Control (EVC) Module allows FULL user control of your exhaust system at the touch of a button. No clumsy key FOBs or additional equipment is needed – this is a 100% integrated solution and the first of its kind for current BMW models.

BMW’s Exhaust Control Valve is integrated at the exhaust system end pipe of the muffler. The exhaust flap reduces the noise level when the engine is idle and when the engine speed is close to idle. This reduces the outlet noise to improve comfort to the driver. The reduction on a stock exhaust system is ~8dB on the stock exhaust system.

The Macht Schnell EVC Module supports the following features:
- FULL control over Exhaust Valve Control at the touch of a button – on the fly or while stationary
- Open/Close Exhaust Valve at YOUR command, or use BMW’s factory profile for Exhaust Valve Control
- Optional User-defined Valve Control Setting at startup (Open/Closed) or default to OEM operation
- Quiet Cold Start in mornings compared to OEM operation
- Easy 20-minute installation process with no wire cutting
- No dealer visits or coding required after installation
- Completely removable at any time

Simply press the BC stalk for +2 seconds to change EVC modes. This is the feature that should have been standard from BMW.

Please click here for more information, and feel free to contact us with any questions or to place an order.

White Paper – Matt’s BMW F80 M3


Our friend Matt (Money2536) is well known around here as having exquisite taste, whether with his choice of cars or stunning home and garage where they are kept. Some of you may remember his LeMans Blue E92 M3 we featured back in 2013, still one of our favorites to this day. We don’t encounter too many with his particular brand of OCD either – and by that we mean the best possible kind. His step-by-step detailing guides are in-depth enough to be on a professional level, and it is with this laser focus he envisioned the first round of modifications for his pristine Mineral White F80 M3.

Ordered with a 6-speed manual and SO interior, this new M car didn’t make it very long before the ideas started flowing, and the results are mild yet effective, as you can see here. We understand the Akrapovic system may be soon departing, but we have no doubt whatever follows will be money, in every sense of the word.

Mod List:
BMW Performance black front grilles
BMW Performance black side gills
BMW M Performance trunk spoiler
IND MW key hole cover
IND MW F/R reflectors
IND gloss black license plate frame
RKP front lip
K&N filters
Dinantronics tune
KW HAS kit
15mm Turner spacers F/R
Akrapovic Evolution full exhaust with carbon tips

CCW Custom BMW F8x Fitment Wheels

We have been working more with CCW to develop several new models and fitments that are BMW F8x (M3/M4) specific. Here is the latest result, with a lot more coming shortly!

Front – 19 x 10 (295/30/19)
Rear – 19 x 11 (325/30/19)
TOYO R888 tires
BC Racing BR (prototype) coil overs
Brembo 380mm BBK Front/Rear

The wheels pictured are a track only setup made to clear BBK and is the widest setup available. These are test wheels – brushed aluminum that has been shot peened and clear anodized.

BMW 2015 M4 Safety Car


From Press Release: “BMW M has always been synonymous with technological innovations, and we are delighted to be able to present another new highlight this year: in the near future, BMW M Division will begin production of a model featuring water injection. Water injection is a system designed to increase the performance and reduce the consumption of combustion engines. We will be using this technology in the BMW M4 MotoGP Safety Car for the 2015 season for the first time.

Increasing the supercharging intake pressure would exceed the knocking limit and is therefore not a viable means for increasing performance. BMW M Division has a solution: injecting a fine spray of water into the collector once more significantly reduces the temperature of the combustion air. The cooler supercharged air reduces the engine’s tendency to knock, making it possible to bring the point of ignition forward and thus closer to the optimum value. This makes the combustion process more effective, whilst at the same time reducing the combustion temperature. On the other hand, cool air has a higher density which increases the oxygen content in the combustion chamber. This results in a higher mean pressure during the combustion process and in turn optimises performance and torque. Finally, the effective internal cooling of the combustion chamber reduces the thermal strain on numerous performance-related components. This not only prevents damage to pistons, exhaust valves and catalytic converters, but also reduces the strain on the turbocharger, which is subjected to lower exhaust temperatures.

The lower process temperatures also reduce the formation of hazardous substances, in particular nitrogen oxide (NOX). Water injection consequently dramatically improves the effectiveness of the engine. Using water injection to increase the knocking limit also helps to largely resolve a familiar conflict in objectives when designing powerful engines. Performance and consumption are not least determined by the compression ratio. This also applies, in particular, to highly charged turbo engines like the BMW M TwinPower Turbo, inline six-cylinder. Thanks to a high compression ratio, this engine is highly efficient and boasts low consumption figures, especially in the partial load range. However, the maximum compression ratio is limited by the knocking tendency when fully loaded. Water injection is also hugely beneficial here, as it reduces the tendency for the engine to knock, whilst at the same time increasing the compression ratio. This way, the turbo engine can achieve optimal performance across a wide range of operating points.”

Duel Pursuits – BMW F80 M3 vs. F82 M4


One of the true joys of having a new and popular BMW M model released is that there are a lot of enthusiasts building their cars right alongside yours. Some end up very similar, yet with small distinct touches. Others might drastically diverge into worlds apart – and this concept is the basis for what you see here today. Yes, if you are wondering, we did struggle to resist the usual “ketchup and mustard” references!

While the team here at PSI knew well in advance that our M4 Club Sport project was bound for SEMA and beyond, through several drastic evolutions, our friend Joe started with an entirely different car, and then continued on his own path. While there are a few basic similarities between our two approaches – mostly in that they are both the current F8x platform – in some ways you couldn’t ask for a greater contradiction. At their core, one is a yellow four-door M3 with manual transmission, and one is an orange two-door M4 with DCT. Night and day comes to mind.

If anything, our opposing processes and styles prove yet again that creativity plays a large part in the art of modifying a car, and two end results at opposite ends of the spectrum can certainly be appreciated by everyone involved. Rather than finding yourself stuck in the rut of having largely the same modifications as several others, realize that there are an ever-growing combination of colors, brands and variations out there – certainly far more than we have installed on these two M cars.

By staging a duel here today, even though each build is worlds apart, we can find a lot of common ground between these two polar opposites. We hope you can too!
