When I first read this post I about fell out of my chair. It is the first negative post I've seen about the HMF pipe. I don't know about the PC T-4 pipe but my HMF is good enough I don't know how there would be much difference in a slip-on. I mean it's just a hollow tube ! Seems like there wouldn't be alot of chances for a different apporoach.
My HMF is kinda loud though. But I heard 2 400EX's with PC pipes & they were louder (IMO) than my HMF on a 650cc quad. The HMF also has a 10 yr warranty on the packing. HMF makes custom pipes for drag bikes & street bikes. They gotta know something about making HP.

 

Where can you get the t-4 for $180?
on the their website they say its $269

here

 

HMF doesn't offer a USFS approved spark arrestor. Be sure your riding areas will allow you to ride without one.

So far, I believe the Pro-Circuit to be well built (don't have a year on it yet but no signs of wear.)

If you buy direct from the factory they charge full list price. If you buy from someone like Rocky Mt. ATV you will get it at the $180-190 range. The manufacturer's do this to protect their distributors since they are putting the pictures in their catalog and pushing their product for them.

 

Realy....
does one of this distributors have a website?

 

Mine came with a spark arrestor. I don't know if it's certified or not though.

 

Mine has spark arrestor too. It is not certified, but looks just like the Big Gun spark arrestor which is. I was told by HMF that a government employee told them it really didn't matter....who knows. The HMF & Big Gun could pass as twins I'm not sure why one is & one is not.

 

Bombrider,
Rockymountainatv.com you can get a t4 for 180 so there ya go

oh thanks tate, thats great, thanks

 

I've had my PC T-4 for almost a year. It looks just like it did when new. I think the quality is good, no complaints here.
