Seeing as i really dont want it loud, i decided to work on the volume before making the proper link pipe.

i made a short link to put the can straight onto the midpipe next to the rear shock - turns out the 2" pipe is just the right size to go into the can, i just had to flare the other end up (to 49.5mm ID if you want to know) to slip on.

I fired it up to have a listen, and.... oooh thats a bit naughty. It seemed really loud, then it occurred to me that in a confined space (an 8ft square shed) anything will seem loud. I've got a db meter app on my iphone thingy so i decided to get technical - measured the sound level with the standard exhaust, the standard CCC can, and the modified can. Odd thing is, at idle they are all about the same, within 3-4db of each other. i cant help wondering if the echo in the shed is making the results worthless so i've pretty much ignored the 'scientific' bit for now

Going by ear the difference is when i blip the thottle - the standard exhaust is the quietest (obviously) the std CCC can has the usual bark to it, but my modded can is between the two.

It was still on the loud side though, so i made another short link- this time with a a baffle made of perforated tube capped off to force the gas to pass through the perf. holes. Try and ignore the dodgy welding please - i did it in a hurry as i was finishing up at work!

pic shows the two short links - i'm sure i dont need to tell you which ones which.



With the baffled pipe its actually quieter at idle than the standard exhaust, i can only wait and see whether its at the expense of gas flow/restriction - time to make a proper link pipe.

on the subject of the link pipe - while rooting round in the shed (looking for something else) i found the link pipe from the CarbonCan i had on my '03 Fazer 600.



it seems to be a pretty good fit, almost too good! it follows the line of the bike pretty damn well and even is the right length to point at the midpipe, total fluke.




i just need to sort the bottom end of the link pipe and then i can ride it and see!
