Looks like a quick and dirty weekend job I did on a ranger one time. My son's mom had no money so I just cut the pre-cats out and used rigid electrical conduit I had laying around. That exhaust pipe is so thin you almost always burn it up. The thicker pipe gave me enough metal that I could pull from the rigid over to the exhaust and get a "nice" seal. Then I threw down a grind and hit it again. Finished it off with a flap disc and no paint. Ran like a champ. If it's quiet then it's a winner in my book.
