broken exhaust pipe

[mudder700]

Has anybody expierenced a broken exhaust pipe on the DRR50's, it broke right at the weld by the flange on the pipe side, it is a solid mount, does anybody mount theirs in a rubber grommet or anything, my son is jumping pretty good, but not extreme air....yet, hes jumping about 18ft on our 36ft tabletop, maybe 2 or 3 feet off the ground, looks to be landing pretty soft, no hard hits or anything..Thanks,Kurt

We had one bust last season right at the cylinder, the flange and pipe actually separated completely all the way around. This was flat track racing, no jumps at all!!

I had one bust on me at the head and then at the silencer i called drr and they sent me a bracket it hasnt broke since

I broke ours @ the silenser flang last year and a freind of mine
welded it for me and last weekend we broke the other end.
Had it welded yet again.

when installing the pipe , secure to head first , and then shim the rear so it does not bind when tightened , if it is binding when mounted it will eventually crack somewhere.
