First post guys...I have a 2007 Chrysler Aspen with a 5.7L HEMI that I just installed a Flowmster 50 on and removed the resonator. Sounds good but I have a perplexing, annoying problem. Under load she sounds great, but if I level off and just feather the pedal I get this fluttering, fast popping sound. More flutter than pop actually.
The resonator had a small hole in it and I removed it thinking that was the problem. Muffler shop checked welds etc, and there are no leaks. I don't hear any whistling.
I'm not feeling or hearing any misses or hesitation from the engine. It has only 74k on her and has never been abused.
Thanks in advance
