When is the non E-tronic version coming out? I love the open valve sound and don't have the funds for the valved version.

$6,000 and no power gains? Yipes. I'd just buy an Akra for that price or an inconcel from Eisenmann - and make power gains.

Sounds really good though. I love the deep tone in closed mode!

1) Evolve E-Tronic Rear Exhaust + Evolve X Pipe with 200CPi CATís, Resonators

The results clearly show there is no real measureable difference in engine power output with the valves open or closed.
The pressure tests show a small increase in back pressure but this is not enough to make any real difference in engine power output. An approximate average increase of 0.10 Bar is seen through the exhaust system.

2) Evolve E-Tronic Rear Exhaust + Factory X Pipe

The results clearly show there is no real measureable difference in engine power output with the valves open or closed.
The pressure tests show a small different in back pressure but this is not enough to make any real difference in engine power output. An approximate average increase of 0.15 Bar is seen through the exhaust system.

Additionally, you can also see an average difference in pressure drop of approximate average of 0.5 Bar before the secondary CATís by deleting the primary CATís. This is why the power increase is so vast from a primary decat. Not just because of such a larger pressure drop but one that is so close to the engine.

The main result is that we do not lose power with our valve exhaust on the quiet setting. To lose power the back pressure increase towards the rear end of the car needs to be very large.

3) The dyno results show that our full system performs to the same level as any other X-Pipe/CAT/Rear Exhaust Setups with both valves open or closed.

I think they are trying to say that the exhaust makes the same amount of power whether the valves are open or closed. The exhaust would still show poer gains over stock

Of course there are power gains as with any exhaust with primary cat delete. Sorry if that is not clear in the data in this post.

The difference is between this graph:



and this graph:



Stock:

316 WHP / 403 BHP and 373.7 Nm Torque

Evolve X Pipe (Primary cat delete, 200 cell cats, resonators) and Evolve E-Tronic Exhaust:

342.9 WHP / 433 BHP and 404.5 Nm

Gain:

26.9 WHP / 30 BHP / 30.8 Nm Torque


I will try and get an overlay of this to demonstrate the gains throughout the whole rev range and I also have graphs from cars that we have dyno'd on our own dyno which I will post later.
