Would it be possible to run a y pipe from the stock catalytic converter to duals at the bumper? If so what would I need pipe wise? ( my muffler and everything from behind the back cat is missing ) if it makes a difference it's a 95 Supercab 4x4 351

For a dual look you are probably better going with a single muffler split into two pipes

Yes, a dual exhaust would be possible for your truck. There are premade systems like the one above, or you can get one of our single-in-dual-out mufflers and have a local exhaust shop build the rest of the exhaust using 3" piping.
