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

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.
