Okay, so I have a 2003 CBR600F4i, now does anyone else here have an '03 F4i...I'm sure you do. Now I'm messin around with the exhaust and actually downgrading back to a stock pipe from an old…let’s say Yoshi slip-on. The can was destroyed in an accident and replaced with an of F2 D&D…which is way loud. I don’t mind the noise…it’e everyone else that I’m going to try and keep happy.

Anyways! What I’m lookin to find out is how many of you people have F4i with that notorious o2 sensor that is located near the midpipe/silencer connection. To keep the California models in the count, there’s a separate listing for them…even though I don’t think that I can relate to them here in Wisconsin…or any of the other 49 states for that matter. So let’s see when that damn lower o2 was added to our beloved F4is

I have an 06 f4i and mine has it, I am installing a two brothers setup with a mounting hole already in the midpipe for it. Non cali model, but still has the sensor in 06...

 

Daym, don't be shy

 

01-05 only Cali models had the o2 sensor. '06 they all had o2 sensors regardless of cali or non Same goes for other bike models and brands too in '06. Some model bikes also added cat converters in '06 as well


My '04 has none

 

Well that can't be true because my '03 has the ol' sensor down there and it's in Wisconsin, slim chance that it came here from Cali.

 

i think you're not getting many replies because you don't have enough options.

 

yeah i have an 04 its a cali bike and i put a yoshi on it but i will agree the D&D is wayyyy to loud

 

Please tell me that's sarcasm...I was only allowed 10 options...and my bike is an '03 so I technically could give a rats *** about '05 and newer [sm=lildevil.gif]

 

'06 FTW

 

want makes you think that it couldn't be a cali bike? geographical distance means very little honestly.
