    CAI, dynomax turbo exhaust system,tinted windows medium on the fronts to match the backs, hid kit hi and low beam, pop and lock tailgate, painted calipers red with caliper paint, put 2.25' leveling kit in front and a 1" block in the rear. its now level and rides WAY better (readylift)>way nicer than the revtek my buddy has i think its garbage imo<, hurst "T" shifter, 18 x 10 american racing (can't remember the name) chrome rims with badass 5 inch lip :), 12 inch rockford fosgate punch with rockford fosgate 600 watt amp, bushwacker fender flares (cheaper than replacing the one i wrecked lol) ,kc light bar with kc lights, toyota aluminum stamped skid plate, and a skull front license plate. More mods to come, thinking a 6 inch lift and arb bumper etc etc.
    I am thinking about cutting the catalytic converter out of my 2009 tacoma 4l v-6 and i was wondering what are some of the advantages and what are sme of the disadvantages? ( i know it will probably have more power :D and the sound will be louder :D but not then i got to watch for bylaw bob :eek:) but im more worried if it would potentially wreck my engine. i haven't even begun to really look at the underside although i installed an aftermarket muffler because the old one was HUGE and CLUNKY the new one isn't bad sounding but its no magnaflow but i noticed a gain in mpg after tossing the stock one out. i know i may loss some mpg cutting the cat out but i figure it could be worth it..

    Thanks to all that post on this thread I love this site and joined only like a week ago !!! GO TW GO!

    It will make your exhaust sound louder for one thing. If your just planning on removing the 2 in the ypipe you won't notice any difference in power, but if you removed all 4 you will lose some low end power, but you gain it back in the upper rpms.

    I Dont think you'll gain anything but sound if u just cut them out and replace it with straight pipe, if u cut out your front two then u will throw a cel and hafta get a o2 sim to correct it. Now if u cut them out and replace them with long tube headers, then u might gain some ponies! But u will still need an o2 sim. To correct the cel.

    Not to forget to mention.... the O2 sensors are there for a reason and will feed certain 'data' back to the computer. Depending on the data, will cause your truck to 'run' differently because the cat isn't there.
