Well I am going to order a 3in buschur dp and tp and bolt it up to my works cb. My question is the rear o2 that i believe is in the cat? I have seen that you can delete this with evoscan? Can I just disconnect the rear o2 and it will run fine? Any cons to this?

 

check engine light will be on until you or your tuner disables it

 

the rear o2 is after the cat not in it. you can disable it or have your tuner do it. OR you can do this mod which i believe works. basically a defouler but cheaper.

No, it IS in the cat. He has an Evo 9. Yes you can disable it without and problems.

 

+1 works great with a test pipe. no problems in 15,000 miles of running it and a tune.

 

i been running it for 55,000 miles and never had the CEL come on. works great and takes like 10 min to make and install
