It's always hard to make an exhaust system which pleases everyone. Some like them loud, some not so. Even in our own case as enthusiasts we understand that there is no perfect exhaust system when it comes to sound level and noise.

Evolve have created a system which appeals to those that like to the best of both worlds with the least amount of compromises.

Main Objectives:

- Noise levels to be sporty/sophisticated with the valve closed
- Minimal or zero drone with valve closed and open
- Power output not to change with the valve open or closed (This is not easy!)
- Valve open noise to be epic without being too loud/annoying
- Easy of installation of the physical exhaust
- Easy installation of the electronics which control the valve position
- Valve operation to be electronic with a keyfob
- Valve system to be easily removed in case of failure (will come with a lifetime warranty)
- A good range of tail pipes
- Tail pipes to be adjustable so individual stagger or length can be setup depending on individual taste and/or rear
diffuser type

The installation of the actual mechanical system is no harder than fitting any other CAT back system.

The installation of the electronics is simple and can be completed within 1-2 hours depending on how the wiring is routed

This is an electronically operated system which does not work on engine vacuum so the installation does not require hose to be routed to the front of the car and plenum removal.

The simple wiring loom goes from the rear exhaust, through any of the numerous gromets on the floorpan and into the trunk and again is very easy to install.

The valve open closing is operates flawlessly and quickly with the key fob.

The sounds with the valves closed is deep and sporty without any noticeable drone. It is louder than stock but very sophisticated.
With the valve open the exhaust takes on a completely different note which is best described by looking at some of the videos below. Minimal drone at crusing speeds.

Of the valve based systems on the market at the moment we have seen many people complaining that the loud setting is so loud that they seldom ever use it. Our system has been designed so that you will actually have a loud setting which sounds great and you won't be embarrassed to use it.

There is no power difference between the open and closed position and this was one of the hardest things to do. It has been reported that many of the current valve systems for the V10 and E92 M3 lose up to 30hp on the closed position and for us this is unacceptable for a performance exhaust.

The finer details have been to place the valve itself in a position where it is invisible from the rear of the car. The rear muffler housings are painted black so the tail pipes are clearer to see and more pronounced. Without the painting we noticed too much reflection from the back plate especially at night and the tail pipes were less visible.

The rear mufflers are also height adjustable to accommodate large rear diffusers or personal taste on position.

The tail pipes have been chosen very carefully based on customer feedback.
