Did you ask ESR what type of porting or engine build to have that pipe matched up with?

Tom told me it was mid to top end but the difference between the TRX 5 and TRX 9 is the TRX 9 hits the powerband harder than the TRX 5.
I also bought it because my cylinder has a dune port therefore I needed a mid to top end pipe for Glamis.

I called them today to see if they had at least some timing numbers to share, but the conversation didn't go technical. He was doubtful Eddie had porting numbers which surprises me. It seems they'd want builders to get the most from their pipes...

By the looks of the pic & seeing the difference between the 5 & 9, the 9 is shorter from the end of the midsection out to where the stinger welds on.
Tail cone being shorter like that would give a little faster wave travel alltogether & would suit the pipe for higher rpm levels of output.

If Eddie does give a port number, probably be around an 83* exhaust

Yea, my guess is the tuned length is a little shorter. 83 sounds like a fun number! :blah: I'm hoping for R&D numbers. I have no idea how ESR works internally with their engineering minds. I want to think they ran some simulations at least before they developed the pipe. Some transfer numbers would be great too. I can't tell that hte difuser looks much different than the 5. If I do get more inside info on the pipe I'll share.
