want to change my pipes at the end of the month,and leave the o2 sensors in the old pipes,so if i have to put them back on they are allready in the pipes,never know about the noise police ,when i change the pipes i will need new sensors, they tell me that the bosch 12028 is the same sensor and can be found at local parts stores,has anyone used these with a pipe change or can anyone tell me if this is the same sensor,--------thanks for all replys,

 

Or you cold just use a Dobeck or other tuner that eliminates the sensors and not have to worry about them. Your bike will need a little tuning when you change pipes anyway.

 

Just reuse the original O2 sensors in the new pipes. Why throw away money on 2 sets when you can only use 1 set at a time....
