Can you provide a link to the slipon version you bought? or is it the same as the link i posted?Hi Scott there you go: (the system doesn't let me to add external links - go to youtube and search with "Arrow Yamaha R3 Pro Race Exhaust System" you should find the same video name).
In the video the Arrow PRO RACE exhaust is completed with the "full racing system" (not just the slip-on).
If you have patience I bought the race slip-on a couple of weeks ago from ebay and I'm now waiting for the delivery. I should be mounting it by middle-end of August (I will be on holidays soon). I can, and probably will, also post a before/after video on my youtube channel. Hope this helps you in your decision.
