So my neighbor had this test pipe that I bought, he said it would change the tone of the exhaust. So I am trying to line up the pipes needed to install. If I buy the cat delete form FS could a muffler shop fit the pipe for a flange connection?

The "test pipe" is just a way to get around regulations about deleting the cat, they say it is to figure out if the cat is bad or not. If the law allows, just have the muffler shop cut out the cat and weld a pipe in. Nothing more to it than a straight pipe that somehow connects the two pieces of exhaust the cat was holding together.

The PO had a pipe hacked in and I want to fix it. Pretty sure the muffler shop can't remove cat, this test pipe is more than just a pipe. I would need the down pipe anyway I haven't seen that available.
