Ah sorry duck, I feel like a tool now. [&:]

ANYWAY ..

I run an Evo .61 with a slimline pitts. I cut the pipes really short and it is LOUD. The one problem I had was not enough backpressure, requiring a rich tune, which led to dousing the plug. I clamped the pipes with a standard clamp and reduced the exit area. This helped a little, but still, the inverted .61 isn't exactly reliable all the time.

Still, it's loud.
