    Just to help you decision a bit... I have the Qtp ORY with dual ecutouts, it is by far my favorite mod i have done to the car, hands down.... the sound is amazing....

    dont mind the camera... it auto adjusts volumes, so its louder than this but you will get the idea.... its teh QTP mated to the stock cat-back....

    i have not gotten on the dyno yet to show this, but there is a night and day difference between open and closed... as best as i can explain it is this....

    with them closed, if you floor it, the car will still accelerate plenty quick, but it has kinda a soffened effect on the power delivery, now open them up, and floor it, the throttle response is soo much diffence, it will in effect snap you back way better than vs closed.... it just feels all around more powerful with them opened....

    Personally i love the sound, but yes i have kooks LT's also... but a cutout sounds good even on a stock exhaust.... but if he is thinkin bout a QTP ORY like that, those are only made for LT's....

    I take "the" out of

    You should go with duals, if you have the money. I bought these from dmh. Both are electric, and work amazing.

    Thumbs up

    If money is not an option than dual cutouts is obviously better in the y pipe but a cheaper alternative that still sounds good and loud is a single cutout under the rear passenger in the I pipe.
    2002 Camaro Z28 Bolt ons, Flowmaster catback w/3" QTP electric cutout, Superchips tuned, Granatelli MAF, SLP cold air induction Lid & filter, ZEX powertune plugs, Taylor 10.4mm wires, 160 T-stat w/fan control, Eibach sportlines & BFG-KDW's on 17" SLP SS rims.

    One off of each side. Better flow. Not in the "I" pipe, but just like the pic a few threads above

    This looks awesome, must sound great! What kind of electric motors are they? Whats dmh? They look different than my QTP electric cutout motor.
