i have a 04 quadcab shortbed hemi.

im planning on ordering an exhaust kit this weekend. im leaning on just buying the aeroturbine 3030 and having a shop weld a custom y pipe. im going to have it dumped after the muffler and no resonators. later on down the road i will add high flow cats and long tube headers.

now my question, does anyone have the 3030? does it offer a nice sound? and performance gains?

also what diameter inlet and outlet should i be looking at 2.5"? 3"?
