Would longtubes with with a catted y pipe hooked up to a stock dual/dual cause the y pipe to hang low? Iv'e been messing around with it for a while now and can't get it any higher. since long tubes go back further than stock headers I'm thinking that there is just too much pipe and it has nowhere to go but down...any input?

I wanna lower the car but will have issues If i can't get the y pipe raised up.
