I'll be interested to hear your feedback testing this PC pipe back to back with the Bill's pipe.

I've ridden the PC Champ Stamp pipe on my buddy's 2026 YZ250 back to back with my 2019 YZ250 with a Bill's pipe / PC silencer.
The confounding factor on our bikes is the difference in reed valves... He has the Boyesen and I have the VF3 system.
We have both cut the heads down on these bikes, run race fuel and dialed in the jetting.

I felt like my bike with the Bill's pipe starts building more torque earlier in the RPM range.
I think his setup with the PC pulls longer on top.

We haven't switched bikes at a fast / wide-open track yet...  (My little track doesn't have space to wring out a 250 two stroke).
The Bill's pipe has been my favorite for a long time on the YZ250, but this new PC pipe is great.

3 motos into my day... The champ pipe has slightly less bottom than the Bill's and a little longer pull on top.

It's a good pipe, but I could go either way between it and the Bills.

From memory, the FMF has a lot more bottom than both and much less top.

The regular PC had zero bottom and a massive top end and I have no desire to ever try that one again. It was just too hard to ride for my feeble skills, but I'm sure it rewards a guy who revs and rings it out everywhere like a 125.

Anyway, the champ pipe will stay on for the time being!
