I'm surprised he'd suggest a 9x8 or 10x6 for that engine with his muffler because the engine likely won't get on the pipe with either of those. Bob Brassel is the support tech here on RCU and he told me if the engine needs to turn 15,500rpm on the ground to get the most out of the pipe's tuning abilities. But if the Evo has enough extra power over say the TT, then you're okay. Testing is the only way to determine that though...
Let us know how it goes. I'm curious to see how the Evo does with the 9x8 or 10x6 props. I'd suggest using APC at the very least as that is the prop brand Dub uses for his testing and benchmarks.
