Flowmaster Quality

Flowmaster Quality
I just recently purchased a 07 Mega Cab with a 5.7 Hemi. I have previously owned an 04 and 06 Quad Cab. I have 1,700 miles on it already since I purchased it last month. I just had a true dual exhaust put on my truck this past weekend with two Flowmaster 40's with 2.5" piping inorder to keep some of the backpressure so I don't lose much low end torque, which I want to work on improving. I have the exhaust exiting out the passenger side, both with nice 4" chrome tips. It looks really nice and sounds great.
I haven't really noticed much of a performance gain, yet, but maybe i will have to wait until I improve the breathing with the new intake coming this week. Should that complemment both of those add ons?
I have always used Magnaflow, with their straightthru design, but I was not fond of the sound. With the Flowmaster being a chambered design, will it hurt performance with a true dual setup, regardless of the intake to come? I intend to use headers latter down the road.
Also, I do not have an H pipe or exhaust crossover pipe installed, but i have room left to install one if needed. Should I install one, or just leave it alone?
Thanks for any help. I look forward to being on this site, receiving help and giving just as much in return. I am 22 and a hard core mopar enthusiast, with this truck, my girlfriends Hemi durango, my hot stroked 318 duster, 1969 Plymouth Formula S 340 Barracuda. I even share a 440-3 powered 19ft Dodge Sportman Brougham motorhome with my Mopar loving father as well. I love them all. Thanks for having me!!!

RE: Flowmaster Quality
You will see gains, but not what Flowmaster rates that you should. All their tests are done on engines with no cats and performance headers as well. You will also feel a little more power once you put the CAI on, not much, but little. The big difference you will see is when the truck gets passed the break in period and you do your oil changes. I got my complete set up with about 2000 miles on, I noticed a change but nothing to bark at. After my truck had a few more miles and got passed its first oil change, now I notice alot of extra power. The new programmer helped alot too. The stock set up that dodge had on the truck were pretty good and a CAI and exhaust alone is not all that much better than the stock set up. These trucks were designed to flow good, and with an aftermarket setup, you only opened up a little better and improved the sound. Give your truck a couple more thousand miles and you will start to see a difference. Also look into getting a tuner.
BTW, I want to see pics of your collection that you mentioned above.

RE: Flowmaster Quality
My cousin was a mgr. at national muffler chain shop for 8 years, and he instists (after I got mine, of course) that Flowmaster has the best sound of all the big name mufflers, and the worst flow!
He has told me that in many cases they flow WORSE than the stock muffler that came off the vehicle.
He swears by Dynomax & Magnaflow, but his personal favorite is a Cherry Bomb......
