need some help with direction with what to go with in regards to downpipe/test pipe. If i swap out the downpipe and test pipe what will happen in regards to O2s sensors...do i need to also purchase the O2 housing? I dont want to run into engine lights, etc. Suggestions on what downpipe, etc to go with also...some info on the O2 housing, etc with doing full exhuast...want to get as much info as possible before ordering anything...
Thanks guys!

 

dont worry about CEL's...get a spark plug anti fouler and stick your o2 sensor into the fouler and the fouler into your test pipe or cat...and it will keep the CEL in check...(meaning it wont come on)...
