Is there any? I would rather not hassle with repacking as I do a lot of riding and 30-50 hours comes pretty quick. Please, if anyone knows, I'm just a couple days away from getting a new pipe but need advice. thanks in advance!

 

is the only advantage to repacking is to get the noise down?? or is it a maintinence thing/? any performance gains?? do you need to clean your muffler from time to time?

 

HMF guarantees their pipes to not need repacking for ten years. That's pretty impressive.

I hear that HMF pipes you are not supposed to have to repack. Something to the effect that where most companies use fiberglass packing, they use a ceramic type packing and then the packing is placed inside a cover. The ceramic is not supposed to burn up like fiberglass and the pillow helps to keep the packing in tact as to keep it from blowing out by chance.

Here's a link to the Wolverine pipe.

the packing mostly just a sound deadner, If loud is not an issue then take it out and it will flow more air. I have no packing at all in my Alien DMC and the inner cap is gone too, it kept blowing out the rivets and coming apart so I welded it up and ground it all smooth. I dont care how loud it is as long as it runs real good.

 

Repacking is not a must unless you plan to ride in sound sensitive area's. If this is the case you should look into a pipe that is easy to repack. If you get a pipe that has allen screws to take the pipe apart you can repack it in 5 min! If you get one with rivets it is a pain!

 

is it safe to assume that my yoshi pipe has packing?? and if so how do i take it out?? loud would be good [img]i/expressions/face-icon-small-smile.gif[/img]

 

Repacking on a performance engine will help power. It keeps the exhaust pressure and speed in the perfect tune needed for max performance. I can tell a difference going from blown packing to new packing on my banshees.

Ceramic is superior to fiberglass.

 

so it would be better to repack it.. id say it has 150 hours on my bike.. maybe only 100 on the pipe..

 

So would I only have to repack every couple hundred hours? If so, that is not as big of a deal. I called white bros. today and they told me that I have to repack it every 30-50 hours. Loudness is an issue too, I would prefer it not to be too too loud. Does anyone know of a pipe that isn't really loud that doesn't need repacking, or am I living in a dreamworld [img]i/expressions/face-icon-small-smile.gif[/img]. What about HMF, I was pretty close to buying this pipe, seems to fit the bill, although I have heard it is loud as well.
