    yeah that's what i thought. Makes sense. And yeah the driver side of the Y pipe is lower because it is against the driver side floor so it cant even move up anymore. it's kind of adjusted to the structure of the under body.

    That is the lowest part of the underbody - the brace under the driver side floor pan.

Get some measurements from the pipe to the ground as well as the bottom of the ground effect center of the door to the ground and I will measure mine and we can compare to gauge your ride height.
    yeah, iunno haha. maybe he meant to say something else. I'll try to get those measurements

You should also have band clamps on your pipes, not regular clamps that could catch on raised surfaces. I think if you got a pair of oval high flow cats, and with some adjusting, you'll be good.
    is that bad about the y pipe looking "fabbed"? :\ youre saying it's a bad installation or somethin?

    It shouldn't be pieced together like that. When that pipe was made, parts were welded together and that pipe looks wavy as all hell. Should be straight and parallel with the floor of your car. Looks like you have low spots at the weld junctions and most likely that's where the pipes are contacting the ground and the floor of your car.

    Don't know if LMPerformance is still a site sponsor here, but I'll use this for reference:

    This is a catless Y from PaceSetter. Note how straight that Y is. Not wavy/uneven.

    From the front and the side, shows how well the Kooks system tucks up:

    That don't look to bad but I do agree with Rich you need to get Band Clamps and get rid of those muffler clamps. Turned to the side you lose floor clearance and turned down you lose ground clearance.

    looks like your Y pipe ends right where the bottom of the car curves, so it kind of tucks right in. Looks real good. Im thinking whenever this guy had the exhaust system installed maybe they cut some things incorrectly, so the pipe doesnt align with the grooves of the underbody, like yours does. Therefore pushing it out.

    If I recall, pacesetters don't come with cats. So I'm thinking whoever cut the Y to install the cats didn't measure right or didn't support the exhaust system while installing the cats causing them to sag.
