Honda CB1100 with Pipemasters 4 into 4 Polished Stainless SteelExhaust

[max]

Houtman i had a good look at the pipemasters, looks very well made and is available on the next island over close to home, but i enjoy the quietness of the standard 4 in 1 and i would not enjoy the extra noise the four pipes produce, sooo.
The thing with the o2 sensor is that it seems to deteriorate over time because the heating element is disconnected as i understand it when the eliminator is used and soot builds up on the zirconium element, that is what i speculate.

I would actually like it if you did install them because they look beautiful and there is not a lot of video about them but i just want to point out the reasons i did not get them ( yet ).
