What muffler would ya'll suggest running on my 70 z? I'm running a long tube header back to my 2.5" exhaust and through a trashed out, boaring, auto-parts store muffler. I'd like to get a tuned, throaty sound, but nothing that is too loud.

Search for "muffler" or "exhaust." We have lots of threads on this topic.

2.25" straight pipe with no muffler is good

Unless you are making over 400hp to the wheels, I would suggest a double ball bearing muffler. A triple ball bearing system would be overkill.
