    I listened to a few of the videos of the XR-1, and that's the sound I am after, but haven't heard one on a 6.0l. I will have to get an exhaust clip of my truck to show what it sounds like currently, it sounds as aggressive as a few of the exhaust I heard while cruising youtube ha ha!! The one pipe that duals into the muffler is all rusted out and rattles and basically leaks and sounds straight piped lol.

    If I decide on the XR-1 3in/out, should I continue out the stock location, or buy a tip and have it dump in front of the rear wheels?

    One question, should I 'Y' after the cats or just pull the cats now and 'Y' it, run the magnaflow and call it a day?

    I've had Borla- sounded good but let go inside, big Magnaflow- annoying, flowmaster- annoying, no one had any spintech experiance at the time, ended up with ss dynomax- similar to magnaflow flow through design but doesn't resonate and I'm happy.

    I've had 2 big case magnaflow's with no resonations... 3 other friends of mine run them on their trucks with no drone/resonating at all.

    For the money the big magnaflows are by far the best muffler all around.
