My cat converters are done and need a replacement so I decided to go with the cheapest option with good rep which is the Kinetix Racing high flow cat converters. Is the Kinetix Racing High Flow Cats a direct bolt on for 2011 M37x? Does it require any modifications? I'll be bringing it to professional next week to have it installed and I'm hoping there will be no surprises. BTW, my car right now is completely stock at the moment if that helps any. Thanks for reading this post. Any help is much appreciated.

I have not heard of these for the M37, just M35. But I may have missed it. Report back how it goes. Did it say on their site they support the M37?

I just contacted Kinetix Racing directly and they mentioned that it will fit the 2011 M37x. I'll report back after it is installed and maybe even put up a youtube video of how it sounds with stock cat back.

Hello,

How do you like them so far?

Any rasp on cold start or when the weather is cold?
