I mean, MY GOD, it is a beast! It sounds so exotic, so aggressive, so clean! And the added power is amazing as well!! This is my first ever aftermarket exhaust, and the biggest purchase I've made for my G. It was worth EVERY penny. Props to Tony for a fantastic product and being so friendly despite my continuous phone calls!

Now onto my issue. I bought a brand new XYZ pipe w/ a straight pipe module on the private classifieds several months back. After installing it, I ran into a issue where the driveshaft U joint was making contact with the straight pipe flange that connected to the OEM midpipe. I decided to take a grinder to it and modify the flange so it would clear. Ultimately, I only took off about 1/4 inch maybe less and the issue never came up again. Upon installing the exhaust, the V2 resonator module that replaces the straight pipe module has become the next subject of the driveshafts onslaught. The spinning driveshaft is now hitting the top of the resonator and I'm assuming has mildly damaged it or made a small depression in the housing. Because of that, now there is a little less noise and vibration, but it is still there. Secondly, the passenger side primary on the XYZ pipe is contacting and vibrating up against the transmission support brace above it. You can feel both of these issues in the floor board of the car and more so hear it. Lastly, the passenger side midpipe that goes over the sway bar is literally sitting on the sway bar. There is zero clearance here. While driving, the movement in the suspension is causing a metal on metal squeak which is VERY annoying. I'm thinking about possibly spacing the sway bar down a bit to aid in clearance. However, I'm not sure if this would put added stress on the end links. Can anyone chime in and let me know what could be causing all these issues? When speaking with Tony awhile back about the XYZ straight pipe issue, he mentioned it could be vehicle to vehicle variances on engine placement and such. I don't believe it is the exhaust itself, because MD has a fantastic reputation for perfect fitment. I think this is a very isolated issue, and my hunch is it may be the XYZ pipe. Tony did confirm from pictures that the XYZ version I have is a very old design. However, any help or suggestions you guys could provide would be very much appreciated!
