I had a leak there also with the stock header and e-series, used some copper rvt. I just put on the Powerbomb and used the same stuff. I don't really have enough time on either one for a long term report.

On my full system e-series it leaks were it comes out of the manifold and where the head pipe meets the muffler part (slip-on part).

.. i'm pretty sure you lose low end if you have a leak

what about for the clamp.. do i go through yoshimura for that? or is there some kind of universal

Replace the copper washers where the header comes out of the head and that will cure your leak there. As for the leak at the header/silencer joint There is a muffler cement type stuff you use there if it is really bad. Mine doesnt leak there too bad. I cant hear it or feel it, but there are carbon streaks there at the end of the day.

i dont know if yosh has a exhaust clamp there. some pipe do and others don't. my sparks doesn't. however, i think most slip on's do but i am not sure.

yea it has one.. but its still too lose when i tighten it up.. i need some kind of exhaust gasket

HA try having it fall apart when you take the whole system off :grr: thats what mine did off my 300 the other day. I took it off to work on it & that baby snapped right in 2 where the header meets silencer!! Ron took it & welded it together though so it should hold now LOL I was probably losing power, we knew it was leaking but not that bad, his E series on his 400 is the same way think he's gonna take & weld his also I wonder why they do that?? I was thinkin it was the weather around here??
