    Yes, you should. If the shape of the pipe becomes an issue try this:

    A single is not going to matter, that will go in the intermediate pipe.... but if you are going dual ecuts, your going to want a new y pipe but to justify the flow needs of 2cutouts, your going to have a healthy setup, this probably already needing a new y pipe

    If your keeping stock manifolds and cats, an aftermarket ORY will be worthless....

    SLP has a ypipe for stock headers+cats but there's really not much gain if you don't go with a set of LT headers.

    +1 for DMH. I have had 4 of them so far. First one replaced under warrenty (my fault, I needed it closed because of parents at the time and used a hammer oops, this was years ago). 2nd one I destroyed because my car was too low, still worked even with scrapping the bottom of it off almost completely. Right now I have 2 of the low profile version. I recommend them, they are great. I also recommend dynamat for the floor though.

    how far after the y pipe should the EC be installed in general, 2 inches 4 inches, ect? Especially before it interferes with O2 sensors?

    My cutout is about a foot or so from the Y connection and actually could of benefited from going even further. Theres a spot in the floor pan that is perfect for the cutout, right before the pipe goes up over the axle.

    Being back there they are no where near the 02 sensors. You can see the 02's better here...

    Just depends on the type of exhaust system you are bypassing with it.

    If the motor is built those gains are possible. I've even read members report 40hp gains on built twin turbo motors. 13 hp seems fair to me depending on the mods on the car, was the car stock?

    yea i dont doubt it either, mine is a whole-nother car when they are open, yea im going from open headers to stock catback with the flip of a switch, but when they are closed, it feels sluggish but still will take off plenty well, but open it will jump out even better, so i do not doubt 14 horse at all....
