Just cut it, and if it all goes pear shape then stick it back together by either soldering it back together or botch it up with duck tape both work. Tried and tested!!!

Welcome aboard!!!!!  You can't buy a sports exhaust for these Chinese scoots unfortunately.  |

The sport exhaust would not produce much more power, as they are desgined for the 2 stroke engines. The 2 stroke enigines do benefit from the cone shaped expansion chamber, however it makes no difference what so ever to the 4 strokes.
What does benefit the 4 strokes is an unrestricted exhaust, and I don't think these are restricted on the BT50QT-9.
I am trying to find out if they are or not, I will let everyone know in due course

Why dont you take all the crap out, fit a perforated tube down the middle of the silencer, pack it with fiberglass wool then weld it back up? Might not go faster but would sound like a speedway bike |
