A few questions first:
1) What's your budget?
2) What are you looking for? Performance? Appearance? Or both?
3) In what part of the world are you located?

I would suggest that you check out this and go from what you find.:

Im located in the states. Ohio. I really like those gibsons but maaaaan they are all the way across the world and are $400. Budget id have to say is probably $300 since i cant seem to find anything cheaper than that (dg's, specs) and the look is finda a bratstyle bike, but thats still up in the air. I already made the mistake of asking if i can ditch the chambers and run a header pipe to a muffler that does the same thing as chambers on another form. Got my ass chewed out. Thanks fellas. Anyone know of a knock off gibson producer in the states??

I have original allspeeds on my bike[gibsons are a brand new version of these]


I would source some pipes that are local to you, otherwise your budget would get spent on post/package

right ..That E-bay add is confusing and Contradicting.
Add says RZ350 but also indicates Fits years 1973 thru 1975 which is definitely RD 350 Air cooled.

I can say first hand that in 1989 when I purchased my first RZ350 With 3200 miles bone stock.
I immediately ripped all that EPA bull shit off it. I took my pair of Tommy Turner's pipes from my 74 RD350 and slapped them on my Z bike. Simultaneously I installed a pair of 78 RD400. The next day I began my yearly trek to Monterey California for Laguna Seca. Jetting the bike en route.

Take the DG P# from the E-bay add and go to the DG home page and verify application for the P# on E-bay ad.
Or just ask the listing on Ebay if they fit your bike. If he responds that they do and you purchase them and the y do not.
ebay buyers protection will allow you to return them for a full refund at no cost to you.

I run RZ350 pipes on my RD400, had to weld new mounts and relocate the kickstand. A little smashing with a hammer to fit the rearsets. . . definitely not plug and play! They have an odd powerband as well.
