Best flowing muffler that'll quiet down my motor?

[DoubleDingo]

Long glass packs are better

Turbos are the best muffler.

Straight 3.5" pipe with like an 8" tip like the diesel brodozers run. Hahaha

I have the Flowmaster 50 delta flows on both of my 454's. Truck has 2 1/2" xpipe, OE boat anchor manifolds, all the way to the back. Not bad for DB's and drone. Chevelle has long tube headers, 3" w/xpipe, all the way to the back. This is a solid roller, rectangular port, quite a few mods. It sounds good to me, but just to loud ! I'm 61 but still love to romp on it, don't need or want to attract attention!

I had Flowmaster Delta Flow 40's on my truck as well.
They sounded pretty good under load, but were pretty quiet everywhere else.
We removed/replaced them for more growl...
