Has anyone seen a x pipe and high flow cat kit specific to a 2004 Dodge Ram 5.7 or do you have to buy the universal stuff. I have jba shorty headers and jba y pipe but i am looking to get rid of the stock cats and add more torque and sound with the x pipe. thanks.
it's easier to do with the 98 than the '04. I'd recommend getting the magnaflow cats, and an H-pipe might be easier to do rather than an x-pipe. The main reason for the cross-over is to balance the back-pressure between the left and right banks, the added tone is just a by-product.
