Can't seem to find the answer anywhere, and the guys on S2KI.com didn't even reply: what is the inlet diameter on the OEM S2000 muffler? I've heard 2" from some people and 2.25" from others.

hrm, I'll go measure it later tonight. Since it's metric, I should be closer to 2.25" why do you need to know the exact measurements? The muffler isn't light.

 

I'm interested in retrofitting one to my GS-R. I read that the pipe is 57.2mm, but others have said it is closer to 51mm. I'm also curious about what the dimensions of the muffler itself are. Thanks a lot.

 

either way, it'll work, are you using muffler clamps or are you getting it welded?

 

No clue yet. I just want to make sure this is feasible before I go searching for the muffler.

I'm currently running an ITR b-pipe+ITR muffler...I want to know if it is 2.25 because that way I can sell the ITR muffler but keep the b-pipe.
