Hey, true dual guys, did you put headers on also? What is the price range for true dual? Does this require a tuner for the ECM not to throw codes?
Thanks

Boxer, doing a custom exhaust won't throw any codes unless you cut out the cats or do anything else to the O2 sensor. Flubbing with the O2 will throw codes some of the time.
