I installed my mufflex Ypipe and 4" system, but on the drivers side, the y pipe does not touch the crossmember bar. Should this be as close to the bar as possible. Also the part that goes over the rear from the main 4" I is very low. I did a search and did not find a side view and a pic of the rear pipe. Did you guys use the clamps? How did you put the clamps on... over the crease where the pipes meet or over the larger of the two pipes. Mine were very difficult to get real tight and when I took it for a ride they loosened.

 

I used the clamps but found out the same way that they come loose. So as of right now I am only using 1 clamp. The only piece that is clamped is the connection at the end of the I pipe where it meets the pipe coming over the axle. That way if I needed to get into the tank, I can just unbolt it and the exhaust comes right off when you drop the rear. I have a pic of the I pipe some where, I'll just have to find it. The only thing though is that I'm not running the exact setup as you, so there may be a difference.

In all, I recommend not using all the clamps longer than you have too. Take it down and get the system welded. Plus if you need they can make little cuts to amke it fit better. If you have any other questions give us a holla.
