So many pipes and choices. Which one is the quietst and most powerful? I need some help here with any one that has had experience with these pipes. Thanks

 

anyone?

 

Definately go with HPd or Hot Seat. Here's about the best tip you can get when buying a pipe for an automatic ATV...ONLY GET A PIPE FROM A COMPANY THAT OFFERS A CLUTCH KIT TO GO WITH THE PIPE. Once you get the pipe and jet the carb, you will not feel much gains unless you clutch it properly. If I were you, I would go for the HPd pipe and clutch kit with the TEAM roller clutch, or if you don't have the cash, just get the pipe and regular agressive clutch kit.

By the way, don't expect a huge gain in power. The pipe will be louder and add some horsepower, but remember, it's a 4-stroke. You can't really get much out of the H.O. motor unless you have big cash to spend. Hot Seat claims 5 H.P. gain, and HPd says 4.5 H.P. gain. I don't think the Hot Seat really adds 5 H.P., HPd backs their claim up with a dyno.

Good luck.

 

For the price I like the supertrapp IDS II it really made my 425 turn on but i already had a clutch kit and it just made everything work.

 

anyone else?

I just put an fmf mega max on mine and i saw a huge improvement in low end performance. I bought it from my neighbor used. He only had it on his bike for a couple of months and it looks perfect. I got it for 75 bucks. A deal i oculdn't pass up. I haven't used any of hpds or hot seats parts so as far as them i cannot say anything. I have had it only for a week now so thats the best i can do

i would look at the white bros they are pretty nice i have one and they sound awesome

 

HPD is a good pipe I have the older style not sure if the new one is the same but I can only see them getting better with research , I love the sound ,deep at idle and a nice bark when cracked but not too loud just right they claimed 4 HP and 5 or 6 foot pounds torque increase I think there claims are reasonable the newer ones are better looking too, AAEN claims 5 HP with there pipe not sure I have never seen one or heard one so I cannot tell you anymore on them. I think the nicest pipe is the Power tech 4 not too sure if there is any increase in power but for looks they are the nicest for the Scrammy. As far as what people say about getting a manufactor that makes the pipe and clutch kit to match them ,Well this might be the easiest way of doin things but it is not the only way, You can match any manufactors clutch kit to your pipe As long as you have a rough Idea where it is making it's power.
Oh buy the way I think HPD is the only one that comes with a bigger pipe all the way from the head to the can the rest use the stock and I think they flow twice as much as the stock system

 

Ive got the new style HPD PowerMaxx pipe/silencer. I havent taken it on the trails yet but rode around the yard a few times. I absolutely love it. I has a deep "potatoe-potatoe" sound that reminds me of a harley. When you crack the throttle it is GREAT. Very deep and kinda loud but not TOO loud. I could feel the low end torque gains as well as the gains of the clutch kit getting it to the ground. My yard shows the scars of testing [img]i/expressions/face-icon-small-wink.gif[/img]
