Default 1000 312r stock exhaust question

Can I decat without the need to tune, fit a Power Commander?

Can I make the stock exhaust louder?

What can I use to clean and polish the underside of my exhaust ( the two sections under seat) which have baked on chain fling, oil, tar etx?

Cheers

I ain't paying that silly money. I can cut the cat out myself, remove the internals and weld it back in place but that didn't answer my question really. If I do this, will it upset the fuelling and lambda sensor or will the bike just run cooler? Advantages nd disadvantages of decat??

Have done decat on my 312 some 10,000 km ago you do not need to retune you must continue to use exhaust sensor , bike will recalibrate to new configuration,seems to help top and midrange not that it was lacking .
If you change to a full open system you will need to re chip, our great site supporters can assist you here , had cat cut and removed from inside pipe rewelded and polished pipe work is undetectable when complete factory stamped logo on pipe all left as standard, it will be a little louder , more of a growl and sound of MV is unique on high rpm change downs - engine breaking

best to remove exhausts - i use fine emery paper then plenty of elbow grease with solvol autosol brings em up like a mirror or a polisher on a drill also saves a lot of work.trouble is the huggers are too short and the underside of the exhausts get peppered with stone chips!
loads of posts on here about set up be careful you can cause yourself a lot of grief and money with this - the holy grail is to fit the micrtech e.c.u. from chris at x bikes this is expensive but results are terrific.
the latest is a guy on the uk forum who has found some one (think it is cjs from the bristol area)who can remap the standard e.c.u. for 250 check it ouit.
cheers colin

If I did mine I would get an Arrow decat pipe, as it is pointless having that can for the cat if there isn't one in it, also there is no cat testing on the bike at mot so i'd leave the rear alone, and fit the decat.

Only my 2p of course

Cleaning the underside of the exhaust - go to Asda and try some green pan scourers (like scotchbrite) and use with soap or wd40, any other oil, or car polish, it will remove it right away. (Tescos ones are less abrasive than Asda, and rubbish)

I've had great luck cleaning my exhaust with Mother's Mag & Aluminum Polish. I works great on ss exhaust and with a heavy cotton rag and elbow grease....it will make an ugly exhaust look brand new....

Size:  209.2 KBWell I removed my two collector boxes, spent 3 hours with a Brillo pad and autosol removing the burnt on oil, tar and road grime and then machine polished them both before re-fitting......6 hours later they look brand new and I can do my hair in them too now
