My aluminized 2 1/2" Hooker Aero catback lasted 14 years, granted only maybe 80,XXX miles. But it took that long for the muff outlets to rust, and then the tube seamwelds heat eroded open at several places on the top along both sides after the H-pipe. I'd go with a quality aluminized again. The Hookers struck me as heavy gauge, and mandrel bent of course.
