Recommendations on exhaust joining?

[Calum]

Had nothing but issues with those bits of rubber mate.

What you probably need to do is fabricate a metal reducer ring that you can close up using an exhaust clamp.

Bikes sound awful as the gap gets bigger.

I've sadly got a gap where the header meets the cylinder and an exhaust gasket does nothing as for your problem I've got a section of braided rubber with two hose clamps that seems to work ok

I used a piece of coolant hose and 2 hose clambs on my dt175 years ago. It held up just fine. I guess you could also use some of that exhaust"cement" that expands and turn solid when exposed to heat (or left to dry) in combination with the coolant hose.

Seems like different rubber hose with exhaust clamps would be the easiest method then. Issue is I can't find rubber hose that thick. 12mm on eBay won't quite cut it..

I've got a stock Yamaha joint at home, of you want it you can have it for postage. I'm away till next weekend but I can send it when I'm home

+1 on the braided hose plus jubilee clips
I go to the breakers and cut a big piece of any old car rad hoses and it will do about 5 bikes.
Works every time

@finnerz89 thanks. I'll keep you in mind, but will try one of the methods mentioned here first

http://www.ebay.co.uk/itm/222426936515 I got creative with this, it's very rigid.

Silicone joiners, high temperature is rated at up too 230 degress.

I have yet to melt anything.

Finally got a roll of this stuff through and it's worked a treat.

Haven't been for a full run yet but just revving the bike up it's nice and quiet again and has sealed the exhaust join very well.

Just one clip?

[Mightyman]

@declan yeah the ones I ordered were too thin so just one for now.

[declan]

@Mightyman ahhh I see

i had the same problem so used a 22mm straight copper pipe fitting then silicon hose and has not leaked since hope this helps
