i was wondering if there is a better method of connecting pipe and silencer then traditional rubber grommet ?
 
DAMN THATS EXPENSIVE! i have one laying in my tool box (FMF new with clamps)

I just used heater hose from the parts store. You can get that stuff for a few bucks a foot. The length I bought made 4 couplers. 2 for me, and 2 new ones for my buddies banshee. I just used some worm drive clamps I had laying around.

I wont pay premium dollar for exhaust couplers after learning about the heater line trick. Stuff has been holding up pretty well (been using it most of a season now and it seems to be holding up great).

That piece posted is very nice. I wonder how long it will go before the O-rings wear out though.
 
i use the heater hose too I:I. BC i have the FATTY header paired with a SST turbinecore2 it didnt match up leaving a long gap. so i used heater hose but it didnt hold up for long before a hole blew thru it. SO, what i did was got a copper adaptor i forgot the size and jammed the SOB in a new hose and clamped it on. so far no issues but i think i small hole is opening slowly. so IMO it does partially work to a certain amount of time. it will work better with most bc they have matching pipes. mine needed a longer hose so
 
You saying its shocking that it doesnt melt? (like wow, how does that work anyway?) or are you saying Im full of it and you dont know how the heater line Im using hasnt melted?

shocked that rubber is used in the exhaust system, Im from the automotive industry, so small engines are new to me. Just funy a piece of rubber is used on an exhaust system. I guess these small enginges don't produce too much heat.
 
They do produce heat, but its in a part of the exhaust thats far enough from the source that it doesnt get all that hot.

On a 2 stroke, the pipe to, and the expansion chamber is really where most of the heat goes. As the exhaust hits the expansion chamber, and expands, it loses quite a bit of heat there, so the exhaust coming out the tail isnt that hot.

So the pipe right there is still hot, but not as hot as youd think. My heater line rubber Im using is holding up very well. I just checked it today. Its probably got 20 hours or so on it and it looks like it isnt dying any time soon.
 
What works good is to use some aluminized duct tape and then wrap the heater hose collar around that , that's what I have and yep it's still going strong , bling is cool , but hard on the budget .
 
Hahaha I just used radioator hose from a junk yard. lol Holds up great. And it looks decent. Smells weird the first ride or so but then your good. lol
