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.
