Inside expansion chamber rust

Wasn't there a thread not long ago where someone cut the stock expansion chamber down the middle to show the internals?? All those little nooks and crannies for sand and small particles to hide OUCH!! for your poor motor.

There were some decent used pipes on e bay not long ago. I'm not sure if there there anymore though.
 
some of yall must have missed that i said it was not a stock pipe, ive ran it since and no problems sounds great

guilty as charged :D, i missed that part.
no worries then

edit: looked back thru the thread and see we even talked about it, duh
