Choosing a pipe for the ATC-500R project

[Derrick Adams]

The 500 needs a better pipe. The beat up old stocker just isn't going to work. So here's the choices available still for the 85 500.

I can get a Pro-Circuit pipe (which appears to be chrome or nickel plated)

or a DG National pipe (Think this is what Billy has on his 500)

or an FMF "Gnarly" pipe (which is also chrome or nickel plated)



So, those are what I have to pick from. Can anyone tell me the power ranges these pipes are designed to operate best at? I'm looking for good smooth power, nothing that will hit hard.

just call up each company..they will help you out...

The pro-circut if its the platinum is a midrange-top end pipe that hits hard

FTZ pipe, looks sick on Mike Hollands, readers rigs page 19

[Mr. Sandman]

I think Kasey had one custom made for his 500R by CT Racing. I'd contact them or ESR and see what they can do for you before I went with one made exclusivley for a 250.

My bike is a CR500 converted. It takes a standard 500 pipe.

[Mr. Sandman]

Your right, it is, I remember reading that somewhere a while back. I guess CRS is setting in.

Yeah, I've got the DG on mine. I've also got an FMF that I tried out before I went to haspin and didn't like it. Took ALL the hit out of the power. No topend at all, and a little bit more lowend. Complete opposite of what I need for my application but it migth work perfect for you Derrick. If your interested in mine, PM me. I had to cut a short portion of the end of it off where it was swedged for the silencer to go in because at the time I was considering on trying to use it in conjunction with another type of silencer to get it quieted down but I never got to it. Its got a little bit of surface rust but not bad.

Also from what I understand, the Pro circuit is more of a topend-ish pipe. I've been wanting to try one out, might be better then my DG.

There is a company called Power Pros thats builds a lot of the pipes for the above mentioned names not sure of a number but ill see what i can do to find it.

Kind of interesting that an aftermarket pipe would kill the power, huh? That maybe right up my alley, though. I really want smooth power delivery for the type of riding I will be doing. Thanks for the tip!

Well, not really kill the power, but they move the power to a different RPM range. Some pipes are made for low-end, and some high end.

fmf is the lowest in low, MTS, is right about the pro-circut, it hits alittle higher and ALOT HARDER, like pullin a good 3/4 sand drag wheelie out the whole hard, the fmf sorta brings out the torque monster more (but how the hell you do that! its already a beast!), the fmf tho does drop off right after mid rpms, if you go smaller carb jetted up, and a weighted flywheel O BOY it will be a tree climber/woods rider, if you go pro-circut and bigger carb/ porting and you will have a OUTSTANDING screamer on top end

[Billy Golightly]
