    What is the best way to run a true dual exhaust with 1 o2 sensor?

    I'm not 100% sure on this but I'll show what I did anyways. I believe an 02 is located on the manifolds on the 94s and older. And the 95+ have em on the y pipe. So I'd either run y pipe with cat back exhaust which is the easiest and cheaper way to go. Lots of kits for it. Another option for full duals is an h pipe. My friend made me a make shift like h pipe with my factory y pipe. I wanted a short exhaust with dual purple hornies on my shorty headers.

    It's not pretty but it works. Actually pretty quiet for what it is. No engine lights. Runs great

    With a single o2 system it just usually stays on the one bank. I would suggest a h pipe or crossover pipe to keep scavenging up good. True duals can severely hurt low end torque if not done properly. True duals usually work best on highly modded motors.
