I don't know, I paid 2 something for mine I think. I got it used for a guy that went to the MRT setup. If you’re concerned about bang for your buck I would seriously consider getting it done at an exhaust shop. For a CAT back with 2-2/5” tubing and a quality Flow Master can you would be looking around 2-3 hundred, installed. Much less if you can get a hook up. Where do you live? Oh yeah, don’t drop the CAT, I hear you loose some low-end balls.
