I'm pretty much at sea level( maybe 50ft ). And yes the Menz 22-10 was swinging it at 6250... the MSC was 6900. So I CUT the tips off the muffler?? I'll see if I have a picture for you guys to let me know if this has already been done( it may have been ) I didn't look and am away at school so I can't go check.

Also would I have to cut the cowl up with the stock?? Does it stick out that far? Oh and noise is not an issue at my field. I'm tempted to see if I can get one.

Found a pic, let me know if you can tell if it has been cut.
