    It won't pass a visual but it will pass the scanner.

    Yes they know and long tubes are obvious. Removal of any smog equipment is a fail is they catch it.

    Not worth it IMO. I would rather have shorties for the low and mid range power.

    shorties and a y pipe would pretty much be a risk too?

    ugh, so many decisions. just worried with shorties i wont feel enough of a gain...

    current mods, Airaid CAI, with TRD cat back

    A Y pipe would eliminate the rear cats.

    So you are worried about not feeling the gains when the intake and exhaust didn't really do too much?:confused:

    You get a longer warranty on the blower if the dealer installs it. The blower itself doesn't void the truck's warranty.

    I understand thr tubes also create a lot of extra heat. Were you going to spray them with a heat resistant coating?

    No more heat than the stock manifolds.

    You can always do like i did on my girl's truck. We installed JBA shorties. Had V-band flanges added to them, so that we could easily swap the cats out for "test pipes". It will cost you more, but will give you mkre flexibility as well.

    Spraying them with coating or wrapping them will void your warranty with Doug Thorley.

    They are already coated from Doug Thorley themselves. Might not be the best ceramic coating, but still coated.

    or just live in a county that doesn't have emissions testing like me. I have a 2012 and im running DTLH URD 4x4 y-pipe, and URD/Magnaflow 3 inch exhaust. Waiting for aFe/TRD intake.

    Or just have your truck registered in one that doesn't have it. Easy as that.
