    Long tubes remove 2 of the 4 cats. Depending on where you live it will render your vehicle unfit for day to day driving via smog regulations.

    Long tubes will give you more performance at higher RPMS, but you sacrifice low end power. Throatier sound from them though. Short tubes leave you with all 4 cats.

    I wasn't aware that TRD made headers.

    And FYI many people on here have the Doug Thorley's will excellent results. The other brand JV whatever the fuck, they are very hit or miss. I'd stay away from them.

    Trd doesn't make headers for the 2nd gen. Taco's. The long tubes will give you more power but most of it comes from about 3500 rpm and up. Cool thing is they are bolt on and you can put them on yourself in the driveway! You will need a oxegen sensor simulator wich tricks the ecu into thinkin that the cats are still there and operating in a normal range. Down side is they are not street legal. The short tubes are supposed to give more low end power, they are street legal but have to have the stock cats cut off of the stock system and welded on to the new headers. That can cost you quite abit of money for labor!( unless you can weld them on yourself) the stock cats flow very well and your not gonna lose much power by going the shorty route! The long tubes are LOUD! Most guys are running two mufflers just to tame the noise and rasp. It's really personal preference as too wich ones you go with. Hope that helps

    Long tubes are not legal because you have to remove part of your trucks emission system.

    screw the emission system if i wanted to be eco friendly i would have gotten a Prius lol jk. no i see why they would be off road only then but here in FL i doubt they really care. so if i get long tubes are you saying i should also get dual muffler exhaust as well. i am running single flowmaster right now as it is.

    Try it with the single FM muffler and if it's too loud you can always add another muffler of resonator.

    Coming soon to a state near you.

    Florida is poised to become a "green" state requiring Cali standards. Even if they do not, tampering with the emissions on an on road vehicle is still a federal issue.

    FYI
