Double din Kenwood stereo w/bluetooth and steering wheel controls and JBL speakers front & rear. Heavy duty battery. Billet grill blacked out. K&N air filter and MBRP cat-back. Just tuned it up new plugs and new front brake pads. Steel powered coated tailgate cap. Billet Grill painted black & factory roof racks. Oh new head lights thanks to toyota.
    I'm changing from my stock exhaust to a new cat-back system. I read somewhere that you should disconnet the (-) side of the battery for 30mins to reset the onboard computer for the new exhaust. Is that true?

    Always a good idea to reset the ECU for any mod that changes airflow, exhaust and intake included.

    This helps the fuel and spark trims to reset themselves in order to get the most out of your new product!

    You can just remove the ECU fuse in the engine compartment for 10 minutes, that way you dont reset your clock and radio presets.
