Quiet muffler recommendations

[Don-T]

My truck had Flowmaster 40s on it when I bought it. I had a muffler shop replace them with turbo mufflers of some unknown brand. They made a huge difference.

My '91 Jimmy came with a too loud turbo style muffler and no cat. Muffler shop put in a Flowmaster Flow FX bullet style muffler where the cat would be and a Walker 21054 Stainless Quiet-Flow with the stock single tip outlet. So much quieter with just enough nice sounding deep tone at idle and wot.

I just bought two Walker 21583 mufflers to run as duals along with spiral flow mufflers to use as resonators. Inlet on the 21583 turned out to be slightly smaller than 3", which I did not like. But likely will just go ahead and try them. They came stock on v10 fords as a single muffler configuration.
