i was wondering how long it would take you, to want a louder voice for your thumper, after hanging out with the harley crowd

debby's bike is quite loud, the muffler i put on it is a mere 17" long and straight thru

i got it free from the harley metal recycling bin (dumpster). it doesn't bother either of us, as the wind noise seems to be a louder annoyance in our ears than the open pipes on either bike. any opening of the exhaust will require rejetting of the carb, and may(probably) void the warranty. supertrapp advertises a slip on muffler that does not require rejetting, depending on how many discs are installed in the muffler.
for a great parts source and dream book for FREE,

go to denniskirk.com and order a parts catalog for the metric bikes, and you can order the harley catalog for the ol'man (brownie points) all the pipes are in there, jardine, supertrapp, cobra, etc with prices and free shipping on orders over $100.00 plus everthing else motorcycle, fowl weather gear (rain is for the birds), leather anything, lights, custom accessaries, etc. etc. kinda like the old sears catalog for motorcycles
