Flowmaster 40's , HOLY MOLY these are loud . I LOVE IT , but I'm going to need to add some type of resonators-GlassPaks at the ends to adjust the sound to get it perfect . The Challenger needs some work on the trunk area to help deaden the sound . It is much louder than my Charger , inside anyways .

Definitely the right choice for back pressure . I do not notice one bit of power or torque drop off at all .

Exactly why I am having the Flowmaster Force II kit installed Monday. It has the additional resonators at the bumper. The system does use the Delta 50 mufflers under the car so it also will not be as loud as your set up but will have zero drone.

I was torn between the 40s and the Blastin Bobs Reso deletes. In the sake of $$$$ I went with Bobs reso deletes. I could not be more happy. Many talk of bad drone, but I don't notice it. Maybe I am just lucky but I love mine.

Different application as you have the Hemi. I believe the drone issue is more severe on the Pentastar cars.

You are correct Scooter. I did not realize he was referencing a SXT. My appologies

No worries brother. I was just trying to keep things straight.

Congrats! Be sure to share your new set up.

I have only put about 30 miles on the car since having the Force II system installed this past Monday but my initial impressions are very good. Just a bit louder at idle with a smooth low tone under throttle. Normal driving/acceleration you can hear individual exhaust pulses. Zero rasp or drone at both highway and surface street speeds. The butt dyno says I picked up a few ponies. Less throttle gives same results as before.

I'm sure it sounds pretty loud. Post up a video when your done.
