I've been reading a lot of post on removing the resonator and putting striaght pipe, smaller resonator or X-pipe on the X5.. I decided to go with the X-pipe from Magnaflow the diameter of it was 2.25". Also i bought some stainless steel piping about 3 feet long and diameter of 2.25". I didn't get much information from one of the forum memeber that went with the X-pipe so i decided to figure it out on my own.. All i knew was that he used a X-pipe and he installed it at a muffler shop and it was detailed at all. I decided not to go to muffler shop because I don't trust them so my brother offer to help me because he is pretty good with cars.. So Thanks alot to him.. We just started cutting off the resonator and unbolt the catalyst converter so it will be easier to weld later. Here are some pics.. and I hope we will complete this in a couple of days and everything goes well..
