    I made my own. After a couple flowmaster setups and a flopro (too much drone), I put in a magnaflow Y with a big 3" in 3" out magnaflow. The ones the suburban uses, it sounds real nice and flows great. I also installed a electric cutout before the muffler so I can blow the windows out of ricers

    I'll bet that catback souds real good. Let us know how it goes.

    5x11x22 will be pretty quiet FYI. I had one on my F150 with LTs and a high flow cat and it was still quiet.

    Oh damn, I wasn't aware that the HD systems could be purchased with smaller cased mufflers now!
