Muzzys pipe testing on stock,std bore kit and 840's

Just got some feed back on the Muzzy reg. pipe vs the pro pipe on a bone stock 08',one with a STD bore kit of mine with stage 2's and our 840 with stage 3 cams. 3 customers of mine had all 3 dyno tuned before going riding this week end. They all were set up about the same as far as the air box goes and with Dalton clutching. I'm not going to get into the dyno numbers right now because they don't matter much once you start driving. These test were done running on the east coast not the sand so this won't be for everyone. I don't have a lot of time to go into every detail(got get back to work)but here is what the final thought was. The stocker ran well with both pipes on the dyno,a little more peak power with the pro pipe. But running in the woods and up hills the STD pipe pulled quicker through the power range where the pro felt flat and ran the same MPH down the dirt roads.On the STD bore with stage 2 cams they found the same thing but out in the open the pro pipe was faster on top end and the pro wasn't as flat in the woods,but they liked the STD pipe better in the woods and up the hills. The pro pipe showed the best on the dyno on the 840. They could not see a difference in the woods with STD vs Pro pipe but again out in the open the Pro was a lot better. For these guys where they were running there wasn't a big enough difference between the two pipe to care one way or the other on the 840,but on the stocker and the STD bore kitted they like the way the STD pipe performed in real driving even if the dyno showed more power with the Pro pipe.

*** One big thing I would point out is that none of these had big carbs or any porting. The pro pipe IMO is going to keep making more power with porting and bigger carbs/throttle bodies so if you are running in the sand or wide open more of the time the Pro will be the way to go.

Again I didn't do the testing but it does line up with the testing I did on our V-Force 700 in the GNCC races.
