slant 6 exhaust sound

I like the Magnaflow round stainless straight through mufflers. The Flowmasters are too loud for my taste. But that's me, you might like them, plus you mention you're running a resonator. To me, there's always a little power advantage with a straight through muffler. Also, the stainless mufflers from Magnaflow are ALL stainless. Even the stuffin in um.
