Silencer packing

[Ozzy87]

Hey guys, I have a set of fatties with power core 2 silencers which are gutted. Is this hurting me power wise? If I repack my silencers am i going to gain a few ponies? Thanks

dude i was wondering the same thing because i jsut gutted my cpi's to repack them and i really dont know if packing helps power or what.. maybe someone will let us know...

You may gain or lose a pony by repacking the silencer, what you will do is your part to keep your bike quieter in an area you need silencers for...and help those of us that have to have silencers (and gulp...spark arrestors) a better name.

 

You won't notice the difference, guaranteed...unless being louder makes you feel faster...

thanks for the input, I wasnt sure if having a big open chamber like that would somehow hamper or affect the flow of the exhaust

I like louder :biggrin: I was thinking of removing the packing for my next dune run!

You WILL gain hp/Tq with packing and core installed correctly on inframes as they need that little bit of back pressure the way they are designed!! You WILL also make everyone else happier around you w/less noise. :thumbsup: Everytime i have ever repacked one w/no packing i can FEEL the difference in torque.

what do u think of good old pink pather as packing?

[Ozzy87]

Ok we have one that says no difference and another guy that says yes, big difference. Does any body else out there have any expirence with this? at first i though it would give me another pony or 2 because of more free flowing exhaust. but then the topic of back pressure comes up and im not so sure anymore. doesn't the amount of back pressure correspond directly with the actual pipe?

I dont think your going to feel any difference. Back preasure plays a big role in 2 strokes,. but m pretty sure that the pipe itself is designed to take care of that. I dont think silencers do very much, other than silence and tone, even though the makers might claim otherwise.

Ozzy, you can do as you wish with the advise but im telling you it runs alittle better with packing. Call any pipe manufacturer and see what they say. We have done it over and over and everytime I feel more torque. Just my .02

[Ozzy87]

thanks guys, I think ill try repacking them and see what kind of difference it makes, then I could put it which ever way gives me more power or I like better.

I read that once the packing breaks down, the exhaust chamber in the muffler starts to create turbulence instead of a straight through flow, which may effect some bottom end torque.
