Here's some good info if you are attending this years on-road nats:
We all know the 1050 pipe works the best with the OS speed 12 XZ, but the pipe is illegal at ROAR events (IFMAR & EFRA legal though
)...some BS about stringer length, sounds like they have a person problem to me. Anyway, I tested the Mugen MSR .12 #P01004 pipe this weekend with the OS manifold that comes with the 1050...it fits, is ROAR legal and works awesome. Maybe even better.
