Okay so got the stock exhaust and put it on. Here's a before: And after: And a bit of represent!!!: Only issue is as you can see the damn bracket that was holding the old can is too big for the stock one, at max tightness it isnt gripping the exhaust. I did actually notice a very slight drop (could be wrong) in power, I actually had to turn up the idle because it went down to 1k revs but it sits happily at 1.5k revs now. But my god did it make it quiet, the induction noise is now louder than the exhaust. I feel like a stealth ninja now haha. Once I get the proper bracket for it the roo racing can will be up for sale for a good 200$ id say. The end.
You may need to adjust jetting a bit to deal with the change in the exhaust to make it run great again.
