Just curious as to how these work, and are they worth trying?
Any info would be great

IINM, the only time I've heard of them being used was in the '86 Plus with the 521 motor. I'll email my bro to find out for sure. He had a booklet from Ski-doo with info on trail & track mods. I think you have to be careful doing something in this area. If too much heat builds up in the pipe you'll end up with motor problems.

Try and get a hold of member Cudney Racing..he'll have the info you're looking for.

Good idea Rocketman

I don't think this is an area where you indiscriminately just start doing things.
