black exhaust cat removal pic
i have just decided to cut open the black expansion chamber that comes with the euro bikes. this has a catalytic converter in to meet emissions regs.
the pipe is otherwise identical to the standard exhaust. i thought i would post a pic to help anyone else who wants to do this. |

Bahh, why didn't I see this before, we missed in first cut.
But yes new pipe for close to free. I then chromed it so could clean it (much) easier. Needs a bit of prep at the chromers as they are a bit 'pitty' under the paint, but was shiny in exposed section so looks & cleans nice. |

Catalyst must eventually get plugged up with oil and become ineffective, I'm surprised they would put one on a 2 stroke...

With the cat pipe swapped on, it ran so lame I'd never have bought the bike - & the pipe hadn't been run - so it wasn't blocked.
With the cat out I can't tell the diff between the std pipe. I chromed it so its easier to clean. |

I did it on my '07 and the pipe is the same as stock with the cat removed.It is still on my '07. Runs fine! It is nice to have a spare pipe around. The '07 cat was in a different location than my '10 is.
