    Take one sharp long screwdriver, place it between the inner and outer pipes at the rear of the muffler, and proceed to remove the baffling, you could go all out and take the muffler off and remove the internal baffles like I did too, it sounds awesome, but it's a bit loud. You won't get any extra power out of one of these motors easily as they're already so highly tuned from the factory

    they are around... the company i think is called BEET but i may be wrong... my pipe has a sticker on it saying MASSERT i think. will check 2mro, best to check at wreckers as they arent bought in to the country seperate from bikes.

    awesker has an awesome condition polished stainless pipe on his CBR250RR, came of a ZXR250C ex japan... looks and sounds the shit.

    good luck searching

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    as far as i know removing the baffles removes back pressure, this can lead to valve damage over time and also as tristan has found it takes a lot of the engines bottom end out... meaning you have to get the revs right up to get the power.

    Ricky at mt eden couldnt tune tristans bike properly because he removed the baffles...

    Do not under any circumstances remove the baffling. Thats done by people who dont know what they are doing. It completely buggers the performance of the bike.

    Yes, there are plenty of mufflers for cibby 250s. Post your question in jdm forums and people will give you a list.

    If you de-rivet them and gut it you loose a couple of KG's... heavy friggen zorsts.

    He (Ricky) could tune it, just under 7k it won't respond well.. like turbo lag. When it does kick in it revs much quicker than it used to, and sounds great in the process.

    If you have to pay alot of money and get a normal aluminium zorst you are wasting your time. (get a carbon one like mr g-dog ).

    I can't seem to find a Yoshi pipe anywhere. Any places you should look out for one?

    short perferated tube, it works both ways!

    Although doesnt look as nice, it sounds fecken nice, and gives you a nice wee power boost, oh and when it backfires, it kills small animals and the elderly - takanini wreckers have them 110$ then alot of work to fit them (custom attachment flange) and new mounting bolt holder, but shit was it worth it.. the extra metal work only cost 90$ - If only I had a weilder.

    If you want torque or a decent bottem end then back pressure is good.

    Reducing the back pressure moves the meat of the powerband up the rev range.
