Updating here, I went ahead and gutted it a couple of weeks ago!!! You where absolutely correct no drone the loudness increase was minimal and the smell negligible!
I ran around with only my racechip and had no ill side effects what so ever. I now have a the bootmod3 flash and love it.
This is a great free mod. Also the cat has two separate cells you could knock the post secondary 02 and still keep the pre secondary 02 cell for a free high flow cat!
I have a couple of pics showing this but I am getting an error message when trying to upload the pics  |
Use the Bimmerpost app, and upload pics from the app! Way easier than using a image resize app. Yes it's hard to go back to having a cat once you go 🐱 less
