So I got the expansion chamber from sick bike parts but am having trouble

geting it installed. I cant get the silicone tubing to fit. It will go on the 3/4 part

but not where it widens. I am going to have to run the pipe up the downtube

and back down puting the end right under the pedal crank. Im using a lot of

little coper pieces. The ring on the j-pipe part of the header broke off(for springs).
I dont hace an oxy/mapp setup, just mapp and propane, so im thinking brazinf will not work.
I bought a product from auto zone called tiger wrap, its for repairing holes in

muffler, but it doesnt seem to actually melt around fittings. I tried cooking some with mapp.

Any ideas or reccommendations. I thought about having it welded up but that

is going to make it more expensive and defeats the purpose og having a

pipe that you can tune and adjust.

My bike is a micargi pantera with a dax bottom end, arrow cylinder and fred head.
