2nd Gen Non-Engine/Transmission 4" MBRP down pipe hitting firewall

[Cummins Thunder]

I am having a problem with my 4'' MBRP down pipe hitting my firewall...



The problem didn't start until I recently did some off-roading :{ The truck hit the front limiters atleast once and I crossed a ditch that caused one pair of the back wheels to come off the ground... I have done this sort of thing many many times in the past, but this is the first time I have had problems with this particular system hitting.

My old 5" system would never quit hitting... I trashed it! now this one after being installed for 4k miles starts banging on the fire wall!! :{



What should I do?? It clears when truck is sitting still but hits when I hit the slightest bump. I am once again starting to wish I had just left the stock system on! Or have had a shop put it on so it would be their problem...



Thanks, CJ

As usual... Feel like I am going to have to go the trial and error route (was hoping to avoid that with some advise).



Thanks for all the replies guys
