Hey, what is the diameter of the slip-on's for your F4i's? I just bought a new Art F4i slip-on exhaust on eBay and the pipe opening is 2 inches. Problem is that the stock pipe is 2 1/4 inches so the mid-pipe does not fit on the stock headers. [:@]

Should any slip-on I get be 2 1/4 inches? or does anyone make 2 inch cans with 2 1/4 in mid-pipes?

 

I vote for the Two Bros. I have the Ti C5-Oval and a friend has the Carbon Fiber C5-Oval. Both sound great. The CF has a little deeper sound to it. For the record, I have never been a big yosh fan, I just don't like their look, and that big japanese logl.

 

Cheers.

Difference is not really noticed in the revs, but at standstill you can tell the difference. With the baffle in its more tame, still lovely growl though. Without the baffle, well 1k sounds like 4k lol, its lovely I got my Micron from the bike shop i used to work in, Streetbike.co.uk.

 

I HAVE AN AKROPOVIC ON MINE IT SOUNDS GREAT...EVEN BETTER WITHOUT THE BAFFLE!!!
