How much louder would the x-pipe w/o resonator make a car with E-race?
And is the pre-order price still in effect? (I realize I'm a bit late to this thread, but if I say pretty-please???)
The change is subtle as the resonators are small. It's more to clean up any resonance depending on what other components you have (ie, headers, cats, no cats, etc.). If you want loud and light as possible, you don't opt for the resonators. Otherwise, it's a preference based on the aforementioned.
Yes, the pre-order price is still in effect. We are going to extend it through October.

Here are some prelim videos of our exhaust system utilizing our new Race mufflers in combination with our other new exhaust components for the M5. I will have sound/video of the Street/Sport (quieter) mufflers soon. Power gains and dyno numbers will be posted as well, but from driving the setup I can tell you the gains are incredible, especially mid and top end. Torque bump is really noticeable at low RPM and sustains through redline. The complete race system with headers is 65 lbs. lighter than stock! Tips are staggered 4 x 90mm angle cut, double rolled edge. More detailed pics of the complete system soon...
Although it's always difficult to tell volume from clips I gather
that's it's way louder than stock?
Thanks for the vids. Looking forward to the numbers as well.
You guys wouldn't have any decibel numbers would you?
Any when will you be able to deliver these items?
Nice sounding mufflers! I have the evo headers with E-race. What performance gains(tq?) can i expect from the addition of your free-flow cats and X-pipe? And I consider tq to be more important than hp gain.

We will have dyno's when final pre-production unit is here. But I can tell you the car pulls harder than it ever did when it had the Meisterschaft on it.

Is it due to the Evosport race mufflers or the X-pipe and free-flow cats? Which parts contribute to the stronger acceleration?
