Shiv and Vishnu have been doing all the R&D possible to make sure that the Xede is safe for all 335's out there. He's done tests after tests, finding out what the limits are and pushing the vehicle to them. If there have been errors or problems with the Xede, they have been corrected. And he has never given anyone a reason to doubt him. He's always been straight forward with every question asked here.
So if people are still worried about the Xede damaging their BMW, then maybe its time to either look at the alternatives or to not modify your vehicle.
Me personally, he's answered every relavant question that I've had, and sometimes more than once. I'm getting the Xede whenever it comes out and the exhaust when I get back to the states for 3 months next year.
