Blue just put a limiting strap on the hangers out of cord from the silencer to the chassis to stop movement and vibration. Putting and h-pipe in that setup doesn't loot too bad on that set-up. H-pipe helps with removal and refitting and side to side movement.

I could make a new H pipe but that would just make it harder to get the system off at the track, I will make a bolt on strap to go in it's place to aid with stability. Pete, the hangers are on the to do list, I can remove a fair bit of heft without sacrificing strength.
Blue I put ( well I didn't put but I instructed someone else to put ) 3 bolt header collector flanges at each end of my h pipe so that at the track it's 12 bolts to undo and the h pipe drops down , has worked well on the rare occasions I have raced in the last few years.
I did think of doing that but decided the work needed really wasn't worth it. Anyhoo, I've finished cutting and tweaking and I'm happy with the fit now. Still seem to be stuck in an endless cycle of aftermarket parts that don't fit though, all very frustrating....
Yes the problem seems to have got worse and worse over the last few years and it generally doesn't seem to make any difference if you buy a premium brand - although the TTI systems are really nice 👍
