Effects of shortening slip on can NC23

Post by willpisme » Sun Oct 14, 2012 1:46 pm

Hi,

Where the bracket connects to the bottom end of my slip on, the actual can has got to the point where the rivets are hardly holding it in place. I think its just worn down and become extremely loose (or been dropped by the previous owner but we will never know!).

The solution seems to be shortening the can a little but was wondering how much is too much before it will start to effect performance drastically??

Cheers for any advice

Will

HI making your can abit shorter wont effect the performance much getting a better gas tight seal at the joint is better bet and makin it safe to use, things to note maybe a slight increase in noise maybe repack while in bits ,if your concerned maybe a dyno run to check fueling to make sure all is ok cheers c

I cut my can down to 8 and half inch, didnt effect performance only after i jetted it and fitted full s/s system and other bits it then effected performance but for the better :).

Oh and yes noise kind of goes out the door lol, but my bike still passes mot with it fitted, even though people tend to cover there ears when im going past lol

couple of videos of mine with the stubby can
The sound on this one is a bit muffled

Sound on this one is alot better, and this was before i put full s/s system on so is a bit louder since this video was done
