I have Flowmaster 40's on my 80 w/true dual and an x-pipe. They sound good but DO resonate at around 1500 - 2000 rpm. That can be annoying when cruising around town. On the highway they sound great with no annoying resonance. Maybe some day, I might switch to Dynomax Super Turbos. For now, I'm keeping the 40's.

You won't be dissapointed, they have no resonance. I have used them in the past, use side pipes now.
Check out the sound of their 05 mustang system. Sounds nothing like a flowmaster.

Some guys say the Flowmasters are too rumbly at idle.

I have the SS Magnaflows and I think the sound awsome. Not to loud, no resonance,and they look sweet!
I think the Flowmasters are too loud and you see them on alot of red neck pickups.

I had the Flowmaster DeltaFlow 40's on mine when I put the 3 inch exhaust on, a low RPM resonance that rattles your fillings, setting off the neighbours car alarm at idle and people stopping 20 feet behind you at stop lights gets old really fast. I put the Super Turbos with 3 inch internal pipes on and am happy with them

You see a lot of pickups with Flowmaster 40's on them because they sound good; not because everyone that drives a pickup is a red neck. I have a great looking '89 Silverado with a nice "built" 350 and a great sounding exhaust. I must be a red neck! So, since I have 40's on my '79 Vette that must make me a double red neck. Loud exhausts do not make a person or a vehicle a red neck. That comes from within the person. That dog does not hunt!

I just got an email from another CF member saying how much he liked the Super Turbos. I had sent him some movie clips and he decided to buy them.
