DIY cat gut

I have been debating down pipes for awhile now my want list is long and expensive. My G35 turned into a never ending money pit and I promised myself ypthe ///M would be kept simple. I decided to do DIY cat gut, I will follow this up with a custom tune from ECUProgram in Calgary. We will see how things go if I decide to do dynos, before, after the gutted cats and after a tune. Anyway I am not sure if anyone else has attempted this on an X5M so I thought I would document it.


My tools



About to start



The hole saw was my tool of choice



With the hole saw you can Tear up the cat material pretty quick.



The material turns to dust



On the edges there is some insulation that peels off pretty quick with the hole saw.





The issue with the hole saw is it's too short



After some pounding with a long flat head screw driver I broke through the first layer of the cat. Then there is about 1/2" of dead space and then another layer of the cat.



I pounded a hole through this layer





Just about done



Done...
