Ferris: On a 660, dual port makes the best gains factory if it came with it, for those with the epa single side exhaust, a large opening does very well for just a little grinding out. I think my 066 is like a 1 inch square hole in size. These are really worth it for these pro saws.

I haven't really played much on muffler mod tests much yet. The dyno is at my buddies farm for better noise control as I live right in a town with neighbours. So I have to drive over to play with it.

Most of the time I've used it to diagnose 661 issues, or a buddy that also has a mastermind 660 that he uses for logging to compare to mine if his has issues.

How many ponies are a stock 660 and 880..cant say i ever looked ?
Factory HP of an 880, best I remember reading, is between 8 - 8.5. That's if the reported factory specs are accurate. They definitely weren't accurate for 660's. My buddy's 461 Chad put on his dyno was spot-on factory HP though. I think I still have that chart somewhere.
