wtb old yamaha pipe.

I have several Yamaha Grunt pipes, actually in good shape maybe one small dent in one of them--will take $50.00 each. Plus shipping located in Springfield Oregon.
what about a vintage 80's B1. I believe it's an RLV, 1 3/4 - 90* - short fat can. ran it on Yamaha, short indoor coke syrup back in the day. haven't looked at it in years, I know it's there and i'm fairly confident it's in good shape.
I will trying to find a pic of a grunt pipe. The pipe I'm looking for is a 90 degree real small can. RLV wasn't out back then.
