This one?I just bought a expansion chamber with muffler from bikeberry Did I just throw my money away????? Any senior help
That type of muffler, like many motorcycle mufflers, is fully serviceable. Simply drill the rivets out of one side, remove the cap, pull the packing and perforated tube out, add new packing, rivet cap back on.I have that muffler and am very pleased with how well it works. I read somewhere that it needs more restriction but I have a 3/4 copper street elbow crimped to fit in the end and it seems to work perfectly. I have it turned 180 as it fits better that way. I have a similar pipe to the BBR style.
I guess it will get louder with time as the glass packing gets filled with oil. Maybe it can be washed out with gas or solvent to bring it back to spec? I haven't got there yet.
Could be a nice flame show if it was washed out, put back on and started right away.
I might just buy another as that is $10 cheaper then when I bought one.
If I bought that pipe, I'd still knock the stinger off and put a narrower one on and shove it in the end half way of the convergent cone.Combine ^that pipe^ with This muffler and you will see a decent lower RPM power increase and keep it from being obnoxiously loud.
