LOL ... I dont care if a 7 year old tells me the muffler will increase my power... if the company he works for tells me it does... and its a reputable company... im gonna trust the 7 year old...

I dont have dyno's because I dont have the exhaust... so its kinda hard to get it on a RR when its not in my hands yet! :wink:

This week or next Eisenhaus will be complete in making my personal exhaust and will be shipping it from Germany to my home... after I install it ill tell everyone what I feel about it... and I can use one of those little plug in things and tell you the difference between my ECU + Filter car -> ECU + Filter + Exhaust... then the change will tell us if its worth it or not...
