I'm hoping someone throws a super 44 on one of these bad boys.

sounds pretty decent.

I put a super 40 on mine. It sounds good to me. 4 cylinder mode can get pretty annoying at speeds over 55.

What is annoying about the V4 mode? Sound? Drone?

[Natek]

Yes. It doesn't sound like a miss or anything. It's just louder and vibrates a tad when it's in a strain and about to click back to 8. I ran the pipe over the axle and dumped it by the spare. Other than that it sounds good. Im getting more and more used to it though.
