I just returned from having the EVOMs ECU & Bypass pipes installed on my Cayenne Turbo. Unfortunately it poured for the entire 50 mile trip so I couldn't really open it up. The rain did slow enough a few times to get a little feel of what they did for the car. As J J would say, DY NO MITE. The extra power is phenomenal. Can't wait to try it in sport mode. I only have 300 miles on it so really want to get a few more miles on it before I put it to the real test.

 

Sweet! They said it would take about 20 miles before it really kicked in. I thought it took at least 100miles. Looking forward to your impressions as you put more miles on.
Enjoy

 

Very nice! What bypass pipes did you go with? Any resonance in the cabin?

 

They are from Fabspeed. I've only seen these from Fabspeed & EVOMS and I wouldn't be surprised if Fabspeed makes the ones that EVOMS sells. No resonance at all. I am not the most technical/mechanical person, but I don't think it would be possible to get any resonance from adding bypass pipes. I think you would have to add/change mufflers to get resonance. Maybe somebody with more knowledge about this can confirm.

 

You're probably right. Any thoughts of competing it's with their maxflo exhaust?
