Default Flow Masters Super 40s how do they sound?

I'm planning on changing out my mufflers too quiet. Don't want super loud but something with a little bark. I've heard the super 40s on a couple of you-tubes posts and they sound nice. Will be putting on a 70 mustang mach 351 4v cleveland. Any one have them? Interested in opinions or getting some clips. thanks

If you don't want super loud, skip the 40's. They're obnoxiously loud and tend to drone in the cabin.

I prefer Magnaflow or Dynomax for a nice aggressive tone without being obnoxious. Flowmaster 50's are also another option.

I love my Flowmaster Hushpower II's, but they're pricier than most people are willing to consider.

I vote no on the flowmaster 40's.

but why do you need a real muffler? go for glasspacks cheap, loud, and fun

Ive got flowmaster 40's on my 351 and it sounds good but does drone at certain RPM's and Im actually thinking about going with the 50 delta flow because I drive the kids around alot.. Its nice but just a little loud for the family.

I have regular non delta 40s on my 65. I love the sound.

My F150 had a regular 40 on it for years. I recently replaced it with a super 40. The super 40 is a bit deeper and a little quieter. I think it sounds perfect on my 95 F150.

Sethalot - I heard the super40s are not quite as loud as regular 40s. Any feedback on that?

I replaced my 2.25" Dynomax Super Turbos with 2.5" FlowMaster Original 40 Series and I love the sound.
