Is the only difference the o2 sensor size?

 

09' didn't have cats except Ca. 10 up have cats

 

09 no cat, 10 cat in headpipe. 09 18mm o2 sensor near exhaust port, 10 12mm o2 sensor down in collector. 09 2-1-2, 10 2-1 (fltrx or flhx)

 

So a set of 2009 aftermarket head pipes will work on 2010 since I don't use o2 sensors anymore. Right?

 

Right

 

Cool. Thanks!

 

So, why do ya not want to use the o2 sensors???

 

probably using a pc-v, or some other tuner that bypasses the o2 sensors.

 

I use a fuel moto tuner. 02 sensors are unplugged

 

Picked up Kury Crusher duals on closeout from jpcycles for 299. Only have them for an 09 is the reason for all the questions. Word on the street is they are re branded V&H duals?
