An update. The pipes showed up and didn't fit. They are Emgo's. The ad says they fit 1 3/4" pipes, but the inlet itself is 1 3/4 with two sets of reducers. The guy I bought them from said the distributor messed up, gave me a full refund and paid shipping both ways. They did look like they would have great tone. He actually paid his asking price for shipping, which means I made $4 on the deal- lol. Awesome guy. Sells Triumph stuff on eBay. He deserves a plug, so here is his store on eBay.
