Default Duals with moroso spiral flows!!!!!!???

I have searched and searced and checks ls1sounds but have only heard like two good clips (they sound pretty good from what I can hear), just curious if anyone else has this setup or has heard this set-up if so let me know your opinions .because I got a great deal on some spiral flows and am thinking about putting building a true dual set-u with them Thanks

I have two 3" Moroso Spriral Flows on my true dual setup. Even with cats, and an x-pipe it is still quite loud. Although, it is slightly quieter than the Bassani dual-in dual-out muffler that was on it previously. Maybe having a blower tends to make the exhaust louder, not really sure.

I like the way they sound, the Moroso's seem to have cleaned up the mid rpm range a little, not quite as "in your face" as the Bassani, more like a weird resonance or something, but cool. IMO, they both sound good in a different way.

My wife runs two 3" spiral flows right off the headers & that's it. It has a really nice deep sound, pretty loud but she likes it. I run a single 3" spiral muffler 2 feet from my turbo then 3" pipe to the rear bumper. IT is very quiet.

Hmmm I'm considering taking off the Dynomax bullets and putting on some different mufflers.
