ill admit my 40 series do drone quite a bit at low rpms, but at idle, WOT or high speed cruising, they sound very nice, imo of course. probably too loud for the average person. but i like loud
Sethalot - I heard the super40s are not quite as loud as regular 40s. Any feedback on that?
i honestly wouldnt know ive never heard the regular one i had melted glasspacks before i put the super 40's on, and jonward786 i love the sig lol

Well I'll let you guys know tommorow - got the super 40s and switching out the summits turbos (way too quiet). I've got magnaflows on my other 70 and I think they are a little too quiet also. I'm looking for something with some bark but not obnoxious. I did have Cherry Bombs b4 the the magnaflows but changed to get a better perfomance system. Even though the magnaflow is suppose to be a better - the cherry bombs sounded better IMO. Hopefully with the super 40s - will get best of both worlds. I'll tell them to clamp in just in case.
just got my 40 thunderbird series today....i am 35..i love the sound..not nearly as loud as i thought it would be.... anything less than the 40 series and i would have been disappointed. the drone that some claim IS NOT THAT BAD AT ALL..

In my last post right about yours, I said that I have had both regular 40 and super 40 on my F150 and the super is a little queiter and deeper. It also has delta flow which reduces interior resonance.
I personally like the sound of the 40s on the Mustangs. A delta 40 will sound similar outside, but not as loud inside.
I agree with phish, the drone from 40's is not bad at all. I can still talk and hear the radio so its not that loud.
Well just got the the super 40s on. They are a lot quieter than I expected. I was concerned they would be too loud - probably the just the opposite. The tone is good but maybe a little too quiet for my taste. Cabib noise not bad at all. Once they break in they should louden up a little. Could be the pipes I'm running too "2.25" OEM manifold. I've got magnaflow on my other car and I would say they are about the same or maybe a little quieter.
