I want to quiet down the exhaust

Lack of tolerance to drone is due to old age.

Im just trying to be considerate of the people around me. I drive through an ally at 5am

Are you running cats? My Cobra quieted down a lot when I put high flow cats on it, even with the slowmaster mufflers.

I considered a set of these on my Mustang and/or Regal. I was concerned they might drone like the ultraflo's I had on the Regal. I've got a set of dynomax super turbo's on my Mustang now and can't believe how badly they drone at 70. I ran them on my previous car and never remembered them having that issue, but it had 4.30's compared to the 3.73's in this one.

If I ever get around to puting a 5 speed in my car I will get them and post up if they work or not. For now I think they would be a waste of time, my highway cruise RPM is 3100 - 3500 RPM, and they would probably be wide open the whole time.

lol, yup! my truck came with a flowmaster and redneck pipes and I can't stand that noise!

40 series mufflers too loud? That's a new one.

No cats?

Yes, that statement was from experience. I have dumps on my coupe and it drives me crazy.
