Jetpro open or muffled guys any sudgestions

[easy]

Which jetpro is better and makes more power the open or muffled type?
'
I think the muffled has more back pressure therefore it will be more tq.
and the open will have more top end power.

This combo is setup with a gp 290 motor which is I heard on the more torque side .

thanks guys

If your talking about silenced, I think the silencer is alot like a gun silencer, it should not effect performance just catch some of the decibels exiting the pipe. I would go muffled and remove it if you don't like it that way you can have the best of both worlds. I think you can also buy an after market silencer if you need one. I love the noise of a pipe, it screams I'M HAVING FUN!!!:cool2:

I'm not sure that you can get an unsilenced jetpro for the MCDs, I may be wrong though. Mine is the silenced one - its still pretty loud

all you have too do is drill out the pop rivets and take out the Wadding so it will be unsilenced or "open" and if you want it silenced again just put self tapping screws in place of the rivets because the wadding should be changed every once in a while anyways .

Yup, it will get pretty oily depending on your mixture and the silencing will be next to none eventually.

pipe

can you really drill the rivets out on the jetpro pipe ??
I know its possible on a motorcycle canister but the jetpro is so small ??
thanks guys...
Perhaps if someone tried both muffled and unmuffled can put some ideas ??

i have .. no performance difference i could tell by my eyes .. just alot louder is all !
heres a rear view of the size of a jetpro exhaust tip .. not small at all

Easy
I have the silenced version as well and it's plenty loud for me as well, the silencer really doesn't restrict the flow of the exhaust only catches a few of the DB's on the way out
