exhaust tips for stock exhaust......

My bike was uncorked two owners ago. I've concluded the intake manifold has been swapped, the needle and jets all swapped and the baffles in the air box opened.

The exhaust is a bit of a mystery. Definitely the stock header and can. But the tip has a polished turn down that I just discovered today can be pulled out!! Out comes three or four little various length pipes attached to the turn down tip. I also took out the guts and have talked with my local Honda guys. We agreed that the inner baffle and screen (spark arrestor) is the HRC piece replacement piece for the stock baffle. It's about 6 or 8 inches longer with most of it being screen.

So my question to all of you is: WTF is the turn down tip and the little pipes that stick into the baffle. Where did that come from ?? I'm going home tonight and starting this bike up without that turn down tip and the inner small pipes. I'll bet it's gonna sound nice...

But I saw a guy on Ebay selling like four different tips for the stock can.
