Can anyone help?

Ask Arrow?

the standard exhaust outlet from the cat to the stock can is 51mm. Arrow is meant to fit the stock can. So id say the Arrow is also 51mm

Arrow header is meant to fit the stock can? Doubtful. I believe the arrow header is to be used with arrow slip ons. The arrow slip on can also be used with stock exhaust via a reducer. Can an arrow owner confirm?

FWIW, I have seen a post where someone installed arrow headers and used the stock end can.

Ok that muddies the water haha. It would be really nice if an arrow header owner just measured it... haha

Yes the arrow headers fit the standard end can. That is what I run

Anything that fits the stock midpipe should also fit on the Arrow headers. The only issue I have seen is that (ironically) some Arrow end cans do not fit the Arrow midpipe.

Did you end up trying the arrow headers, yoshi do a set that are meant to fit the r11 slip on but I have been told they don't fit the alpha?
