Fitting a Racing Exhaust to Your Motorbike

This is actually a very simple and easy project, no monstrous mechanics job, in fact we did it in five minutes, though it'll probably be slower first time round.

The bike in the photos is a Honda CB500, the exhaust is a Remus...

Step 1 Tools, Materials and issues

Well before I begin there are a few legal issues to explain about this, starting with the fact that if an exhaust states "not for road use" it's not strictly road legal, now as long as it doesn't strike the decibel levels that will get you pulled over it's fine day to day. However you will have to put the stock exhaust back on for MOT, mainly because they can point to the writing on the exhaust that says "not for road use" on it. Some people take to removing these embossings in various ways - A simpler solution would be to seek out an exhaust with a removable baffle, meaning it's road legal and you can just stick the baffle back in for MOT tests, rather than keep the old exhaust in the garage and change the whole thing every time.

As said the project's not a tricky one.

The hard bit is finding your exhaust, do your research and know what you want from it, the Remus pictured is a racing exhaust and has certain properties, it's notably lighter in comparison to the stock one, steel versus aluminium so it's not a big shock that it's lighter. It also tends to burble and crackle under normal engine braking and if you do it in a low enough gear on purpose it backfires, loudly. That's good for some and bad for others...

Anyway, Tools and such:

- Spanners, allen keys and a socket wrench, it'll vary bike to bike but those are the main things you'll need.

- Can of WD40 or a better penetrating oil

Note: Remember to let the exhaust cool down before attempting anything, it can get fairly toasty even after a short ride...

hi iv'e got a honda c 50 super cub in my garage, i want to remove the foot pegs and bracket to clean it, but i need to remove the exhaust first as it is in the way, does anyone know how i do this?

Cant think of how the exhaust goes on a cub but if its one piece you'll likely need to remove the header bolts and a bolt somewhere along the exhaust...

If only cars where this easy.... I just got rid of my Honda CRX that had a bad muffler that I didn't have the patience for.

Actually if the retainers and downpipes are in good nick a car can be simple enough, though it does depend very much on the kind of exhaust and it's layout...

Nice.   I remember as a kid  much younger person putting a Quiet Power muffler on my VW bug.  Pretty much the same principal except I had to re-tune the engine because of the decrease in back pressure.

Powersport Hondas like this usually have a graphite gasket at all the pipe connections. They should be replaced.

None to speak of, though the bike's old and recently just got written off, the sleeves were all a great fit though.  Not sure what's gone on there, unless... That's CB but not a CBR admittedly I don't know the exact details of hondas but powersport...
