Default Flowmasters Anyone ?

I'm considering the Flowmaster #17217 Cat Back System.I understand that it Does Not come with the 50 Series Delta Flow Mufflers that have a 3 Chamber Design which is their Least Interior Resonance Prone Flowmaster design Available.They use the Std. 50 Series.

Anyone Running This Set Up and is there a Interior Resonance Concern?

Thanx

Yep, I just have the mufflers and true duals w/ cats. I think it sounds great, no resonance at all!! Makes the car sound like a Corvette, but will not make you want to pull your hair out on a long drive.
I love it.

That's what I'm considering. Don't get the whole Cat Back System just add the Series 50 Delta Flows with maybe an "H" Pipe in place of the Resonator..

I have a single super 44 inplace of my cat with dual outlets and it has no resonance at all between 1400-2000. It's actually very quiet, which I believe is to do with my cam, but after 2600 it's loud as hell - somewhat moderate resonance but just overall loud from behind. If I had the stock cam, I'd say it may resonate a bit, but considering mine is the least restrictive muffler of the 40-50 series, 50s would be a lot quieter.

If you put in a flowmaster, you'll get more compliments on the sound than complaints of the resonance, guaranteed.
