Recommendations on exhaust joining?
-
Over the past year there has been a gap forming in between my down pipe and silencer to the point where I could put my hand over the silencer and the bike would still run fine but start pumping out the exhaust fumes from the gap. I noticed this as I finally noticed the bike sounded quite loud considering it had a stock pipe.
I took the entire system off yesterday to try and join the two sections a little better. I noticed that one of the metal "flap" kind of things that actually slips over the down pipe had bent inwards the last time I remove the exhaust. No wonder the gap was getting bigger...
Covered the gap fully with foil insulation tape and the bike was virtually silent again (Love the stock exhaust) ! Took it for a quick ride and it pulls hard past 6k again
The foil tape didn't last too long and a small gap has appeared again.
Any recommendations on what to use to join them properly?
Not confident on spending Β£10 for a bit of rubber I'm not even sure will fit my bike (TDR 125), as the exhausts do differ slightly.

At this point I'm even considering a small length of hose pipe??? Need a bit with fairly big diameter and has to be heat proof of course.

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.

+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 -

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.

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