Chris - like you mentioned the Sweet Thunder cores were smaller - around 2-1/4". I could also produce the 2-1/4" core w/3" outer body & modified ends to slip inside a 4" straight pipe - same as my Corvette inserts that are also chambered with the crimps - called "POWERSTICKS." None of the Cobra owners so far are showing any interest in running actual chambered pipes. This would produce a quieter tone (with the 2-1/4" core), plus a different tone than the "Glasscraps" someone else is referring to most Cobra mufflers as. Basically, you are all running "glasscraps." Anybody up for a 2-1/4" flowpath chambered insert?
