Flowmaster one chambers on 11/12 Gt's

There are a few guys in Columbia, Sc that have done this with their 5.0's. I haven't heard it yet nor seen any clips online. One owner told me on the phone that he left the resonators on and it sounds great (no resonance at highy cruising speeds etc). He also said they added a few ponies on the dyno. Anyone heard these on 5.0's??
 
I have them on my 5.0 and I love the sound. I did an axle back with resonators on as well. It's pretty aggressive but I absolutely love it. No idea if I got any more HP since I haven't been to a dyno. Only complaint is if I'm running 55 and put in 6th there is some drone so I just leave it in 5th at that speed so no biggie :nice:
