Lost power with new can.

[Mach_1_Man]

I have a 2002 summit 800 HM with DPM. I put a can on it and and have lost my top end speed. I can only get about 70 mph out of it. Low end power seems good. Does any one have any ideas how to fix this problems.

Put the stocker back on if you want your power back. Most cans claims to boost HP is BS. Good for weight loss. Bad for HP and noise.

the only can that actually makes power is the mbrp & its only like 0.4 hp gain, thay generally dump to much back pressure, that a 2 stroke needs to help burn the fuel/air charge

I agree cans do nothing but make noise and lighter, but now way it dropped 20-30 MPH installing it, you have other issues. You wont gain with a can BUT you wont lose either JMO Ive had many and never lost any speed.
