Received and installed the Sil Moto's yesterday. Very nice quality and fit well, did have to cut one of the stock exhaust clamp bolts which was frozen solid. To my ears they are a bit loud but the sound is so good who cares [/URL]][/img]

Looks good - where did you get your header from and what was the cost? Thx

Why wouldn't these fit any other Monster? Aren't the header diameters the same?

I got the Marving header/midpipe from Monsterparts for around $350.

The listing states the Sil Moto cans will fit the S2R/S4R. The exhaust collector boxes (udders) on the S2R800, S2R1000, and S4R appear to all have 43mm outputs. Not sure but i think the S4RS has 50mm.

TY - now I need to decide If I a need a midpipe  too..

I don't think there is a lot of performance to be gained by replacing the udder alone, for me it was purely a visual thing. Love the look of the S2R but my eye keeps going back to that collector box, it just bugged me. A full Arrow or Termi system would have been nice but could not find any mint used ones out there and could not afford a new system all in one shot. Good thing about the slip-ons is they will work with the udder or any midpipe designed to replace it.
