Default Running straight headers
I plan on taking the exhaust off my blazer in favor of straight headers. How long of an exhaust pipe do I need to have after the collectors so that the O2s don't go crazy?

12-14" should be fine.

Well, this is in my mud truck/blazer in my avatar, not my daily driver. Stays wot most of the time. Won't take but 5 minutes to swap out if I don't like it.

Open header sounds semi good at idle..once you drive down the street it turns in to a tractor. HORRIBLE! I did it, rode on the street and turned around immediately with a bad taste in my mouth and a headache.
