Does anyone know if theres a company that makes a off-road y-pipe that doesn't have cats built into it for the 5.3 motors? I want to ditch the cats when I install headers. I already have a dynomax bullet race muffler on my truck and man does it sound good but I gotta get rid of the cats

 

I've never seen an off road Y-pipe for a 5.3, I'd just have a local muffler shop make one or if you're really making power ditch the y-pipe and run true duals.

 

you know i had a custom built one that was bought and it had a flowmaster end on it. man i need to dig up who i got it from and see where they had it made and where the end came from.

 

jsut cut the cats off and weld in 2 peices of pipe. also with just one bullet and no cats it will sound like ***. it will pop real bad and be very raspy.
