Until we get our updated kits from Yamaha, you may consider doing the side panel mod yourself. Heres some pics for those interested.

Matt,
Those really look great!!!! I was talking with Kevin at Port and he told me about a stock pipe mod for the Grizz and then bump up the jetting and needles. I guess it really rocks.

Tom, I have also heard of the stock can mod. You basically drill holes on the end of your baffle (in end cap) and jet to 170-175. I talked to MHF and they said that mod really doesnt do that much for HP gain. The new Eco-System can will be ready late next week. HMF confirmed this to me this AM...BBY
