Will anything be affected if i extend my o2 sensor? B/c I got an ls one where it connects to the down near the cat, and I want to wire up to the top of the down pipe near the headers. Because the turbo downipipe i got has it there.

 

It will be fine, I extend/shorten them all the time..

btw as much as I like your avatar its to big and needs to be resized
90x90

thanks,
jeff

 

Make sure you have real good conections soldering is best and heat shrink it after. Oil on a bare wire can change your vaues

 

mine was just extend.. from #4 header pipe near the port to the collector near the cat. runs fine.
