This has nothing to do with what we were talking about, but my last exhuast hanger finally rusted through and I was dragging my exhuast down the road. I cut off all the rusted pieces between the cat and muffler. I want to put on a deep note muffler and dont know which to buy. Should I take the cat off then put the new muffler there or after the cat. I dont want a super loud exhuast but I want the deepest note possible. Thoughts?
