I'm building a 99 Tahoe 2dr 2wd in the next few weeks I'll be installing a set of JBA Headers Competition-Ready Headers 6830SJT, 2 Thunderbolt high flow Catalytic Converters, 2 Flow Master Mufflers and a complete 2.5" dual exhaust system. Along with a full ported and polished TB.
Right now my engine is pretty much the stock fuel injection with a Volant Cold Air Intake. (Eventually it will have the marine intake along with an ATI ProCharger.)
What I am wanting to know is with such a free flowing exhaust should I install heated O2 sensors? Should all 4 be heated or just certain ones? If I install heated O2 sensors where should I get the key on power from?
Thank You
