I thought I'd make a thread to keep track of ESR's status, unless one already exists that I didn't see.
placed an order for the trx9 pipe on the 7th, and from Oregon to AZ arrived today the 12th.
Looks like the 5 and 9 are available.

trivia about the pipe... The original hydro-formed 9 runs well with my porting/setup, though when I first developed the engine, the 5 ran very similarly to the 9 on the dyno. I suspect the tailcone is the only difference between the two, but I find it hard to get accurate measurements from hydrofomred pipes, so I don't truly know. However, the diffuser is still hydroformed, which also makes me think it's a shared part between the 5 and 9.
Anyway, the center section and rear cone are hand coned now looks like, and is angled slightly differently. I like the new name-stamp too.
