i dont think thats possible unless you manually cut the cats and relocate them..

you would need short tube headers.. or get long tube with high flow cats like the ARH ones...

long tubes basically change the architecture of the headers design making it more efficient and making the place where stock cats are non existent

Not possible. You want long tubes and race cats. To use the OE cats, you need to use shorties. Shorties will give you a nice sound, but not the big hp bump as LT's. Especially since your still restricted by the 4 stock cats. Race cats flow a whole lot better.
