Honda CB400 Super Four exhausts?

Hi. I've just bought a Honda CB400 Super Four 95 NC21.
I'm wanting to change the stock exhaust to an aftermarket exhaust. Something that sounds good is slightly longer so it reaches near the end of the bike and goes up slightly higher more sportylooking likehornet.

I just can't seem to find any exhaust specific to the bike. I think with the bike being a jap import makes them harder to come by. But I've seen a good few superfours on eBay with different exhausts. I just don't know where to get one from lol
Any help would be appreciated

Scorpion, Viper, PRP and Xtreme Stainless all make exhausts or silencers for the NC21. If you're really pushed for cash, Lextek also offer silencers, but Lextek is Chinese…

If you're feeling flush, you can get a complete system made up, to your spec - but it won't be cheap.

Go ahead; and debase the performance.

The simple and easy job would be to cut off (If your original silencer is welded onto link pipe) or unbolt the original silencer. Then install a slip on silencer of your choice. All you need to do is find out the outer diameter size of your link pipe (At the end, where you cut / un-bolted original silencer off). Then you find out the inner diameter size of the after-market silencer you like. You want it 1mm-3mm bigger ideally for a tight snug fit. You can also get silencers with a bit bigger diameter than that to fit, but you'll need to get a reducer.
