Well last weekend I got a magna flow muffler put on and a 2 1/4 pipe from the 2nd cat back deleting the resonator. I also added a drop in K&N air filter and did the whole tape thing on the intake tube. I think this weekend Im going to redo the tube. I also have a sprint booster on order should be here anyday. I love the new sound of the Magna flow and it really brought out the sound of the intake now. Its also running a whole lot smoother now for a justa.
