Neither.....Spintechs....or the good old Flowmasters.....
had spintechs, just sold them, i liked them on my 302, but they are way too loud on a motor that can actually make noise on its own.
and ive got about zero use for a chambered muffler, so flowmaster/mac etc. are out of the question.

You'll like the Dynomax...they just sound more smooth and tame than the Magnaflows.
For a general comparison, this is a guy i know who has a long rod 306 and very similar engine setup to mine except he has Dynomax mufflers. Listen to his clip vs. mine and it'll give you an idea of how different they sound. Still good, but different. The downside IMO to both mufflers is the idle sound...i just don't care for how either one sounds at idle.
