Opinions on sound is subjective. I like 3” Dynomax Ultraflo’s or open headers with extensions! One thing I think makes any muffler(s) sound crappy is small diameter pipes, especially tailpipes. I see and hear so many nice cars/trucks around but can only frown when they Rev the engine and all you hear is that raspy “brappy” noise coming from dinky tailpipes. Gotta be 2-1/2” minimum all the way or 3” if you can make it work.
