probably a dumb question,but Will running open headers for 2 days, besides being obnoxiously loud affect anything?till i get my y-pipe in....:ugh2:
i can get one fabbed up but dont really like the local muffler shops pipe bender.leaves kinks worse than the factory y pipe kink lol
You could have them make it out of oversized pipe so that when it kinks it the size will be closer to what you're needing. That would get you by for now until you can get some mandrel bends. Running open headers is going to make it run very lean.
i fouled my plugs running it open exhaust.
i never had issues, i ran mine like that for 2 weeks
haha just went to the store and engine light came on...who knows what code it threw
banks 1n2 bone dry
my rear 02's are deleted already,,is it ok if i remove the sensors,or do they still have to be plugged in just set aside?
thats strange i ran open headers on my yukon for weeks with out a single problem. well almost i ran out of gas much faster.:thumb:
My understanding is the rear 02 sensors are not deleted the check engine code that rear 02 set is just turned off (unchecked in the tuning program) but the sensors are still working/reading/sending info to the pcm. I would unplug them because if you just set them aside plugged in they would be showing very leanQuote:
