At the risk of hijacking the original thread, has anyone got experience of fitting a standard full Single cam header and can system to a Twincam bike?
Did it make the bike quieter?
I have removed the flappy thing from my TC so that it can't seize, but now its i bit too fruity for the neighbours when i'm coming and going at odd hours. I need a little less throb and parp!!!
The full SC system will fit straight on to the TC but I can't see any advantage doing that for what you are trying to obtain.
Some feel that the TC silencer is slightly less restrictive than the SC silencer, hence the flappy valve. Nothing definite though.
The standard system, with or without the flappy, produces the best power with reasonable noise.
My TC is the same as yours at the moment, standard without the flappy. I've tried different systems including a full de cat SC sport system and an old set of standard TC headers with the cat removed.
All other options apart from stock are going to be LOUDER.
Don't start faffing about with aftermarket silencers and homemade baffles. It'll cost money and if you do manage to make it quieter, you'll almost certainly lose performance.
The best aftermarket silencers, like akro, are going to be slightly louder than stock and produce the same power as stock. So unless you're after more noise and the look, why bother?
If you want quiet and keep performance, you'll need your flappy again.
I like the flappy valve and think it works well. Keeping the bike quiet when necessary and a bit more vocal when opening up a bit.
Only changed it recently for something to do. It'll probably go back on again at some point.
I've 40k miles on mine now and a bit of preventative maintenance with WD40 seems to have kept it working ok.
I believe there is a silencer by Mivv(?) that's quieter than stock, but again, it's very likely that you may lose a bit of performance over stock.
