gl1500 exhaust part missing

Postby virgilmobile » Sun Mar 18, 2012 7:49 pm



Here's the story.My new 88 is obnoxiously loud.The droning noise rings in my ears so bad I can't hear the radio at 45 mph.
Yes it has(had) the aftermarket,cool looking triple pipe add on tips.
I took them off,no help,I tried a turn down 12" extension,no help.
Finally.....now don't laugh at me....I shoved a valve spring into the end and secured it there.(noise disruptor)
WOW....a 50 mile ride from 25-55 mph and 80% of the droning is gone.
Sooooo.here's my question.
I suspect that there WAS a resonator baffle in that tip that was discarded.The exhaust ends in a short 2"pipe.What is missing?,what's it look like inside? and where can I get one to return it to a factory sound.?(quiet)

Might be the muffler has internal deteriation and exhaust is blowing straight through. Stock mufflers on my bike rattled like a box of marbles from interior rot and was alot louder than the current Daytona exhaust.

I looked really close at the inside.There's a little flaking,but everything is intact.It's clean and nothing rattling inside.The tail end of the exhaust is a 2" stub with a hole near the end where the tail would have been secured.
Obviously the PO removed it to add on the triple tail pipe.
The original tail must have had some kind of baffles in it to reduce the roar I hear all the time.

I found a pix from another site.it shows what's missing on mine and it does have a resonator in it.
Does anybody have a set of these in any condition?

Thanks,I would prefer to keep it original.
It seems that it may also change the back pressure in the exhaust system,as it runs better with my home made packing.
I've made some baffles out of brass drain pipe and steel wool that work pretty good.

I just wanted to say THANKS to tmilam
He saved my sanity and provided me with the missing tips for my exhaust.
It really cut the droning I heard in my helmet.
