got a new set of downpipes for the car, and this is the information that i was given in a message...
"straight pipes delete the rear cats, you can have them coded out/work out an o2 defouler/spacer setup"
basically, i have never had to take a car through emissions, so i dont know what they check and if i delete the rear cat and code it out, if im just gonna have to put one back in for the emissions testing.
if they dont do that sort of check, then how do i go about just coding it out? Or, is it something that i should just get the spacer for?
