Ok this is the next evolution for me. Originally I had decided on the Sato Slip-on only for my bike, but when I started getting emails & messages asking if the new Box Style Full System designed for the 06-07 1000RR would fit on an 04-05 bikes I simply didn't know nor did Sato Racing so we decided to find out!

The answer is YES it does fit on the 04-05 1000RR & it is quieter than the oval Sato Slip-on I had installed previously, but has a much lower & meaner sounding frequency. Much more neighborhood friendly at idle or low revs, but still sounds like full-on Superbike once you get above 7000rpm

The install went as easy as can be expected for any full system, but I did have to use a few washers that DID NOT come with the kit to adapt it to the subframe of the 04-05 model bike. No big deal as I had them laying around or worse case scenario it would have cost me about .79 cents at Home Depot...

I will be testing the exhaust on the track this weekend at Road Atlanta without any of the OEM heat shields installed to see if there are any heat/melting issues to be concerned with etc. Check back here for the results.

Found a problem with the 04/05 model installation:
There is a rubber sheath on the radiator hose closest to the number 1 cylinder header pipe. During the weekend on the track I noticed that when the engine was at temp and the coolant system pressurised the hose would expand & it was melting that rubber sheath around the coolant hose. A friend of mine (Tom Moffat) had witnessed a similar issue on the AMA Superbikes & found an aluminized piping to fit around the hose just like on the Factory bikes. I'll get with Tom & find out where to purchase this piping soon & report back here.

Just out of the box
