    I think its personal preference if you don't have inspection...depending on the exhaust you have and what sound you like. It will sound more raspy/ORY but I have been told it will net you small hp gains.

    ORYs are great...for creating rasp. Choose your catback wisely and rasp won't be an issue.

    +1 on the ORY creating rasp. Although, mine is finally under control since I've installed my Hooker Aerochamber muffler.

    tg580, you'll love your car even more with the LT and ORY.

    Talked with the guy who makes the LSXtreme Performance catted-y I am purchasing and he explained that much of the rasp you hear from the ORY is due to the merge. He explained that with an excellent flowing merge you can eliminate much of the rasp. Just something to think about- so if you don't want cats and you don't want the rasp, get the best flowing ORY you can find. Keep in mind, I've never heard it, so I'm only repeating what I was told by someone who designs exhaust for our cars. Personally, I'm going with a catted-y, not because of emission requirements or because of rasp, but out of peace of mind. If I end up selling it or end up moving to somewhere that has emmission requirements, I didn't want to have to buy another Y.

    Your gonna have to put up with that gas smell and with your car running rich until you have it tuned. If its your daily driver I would leave them alone.

    From what I've read, you will be very happy with LT, ORY and Magnaflow catback. Magnaflow catback doesn't rasp.

    I've heard that too, but I've also heard that nice merge (ie the flowmaster merge) doesn't always fix the rasp.

    I have magnaflow catback and thunderbolt high flow cats. It sounds amazing and I cant wait to add LT's. If I could id probably ditch the cats.
