Our customers have told us that they heard a slight increase in volume but nothing to be alarmed with (if something you do not want) or happy with (if you are expecting volume) and that they did notice a tad more rumble as well.
Hope this helps
I will chime from my experience with my exhaust set ups.
These all involve a flowmaster supper 44 muffler.
Straight muffler swap- was alright
pipe chopped 4" after muffler dumping around axle- stupid loud with bad box echo.
Welded resonator and tail pipe back on- back to nice but not loud enough sound.
Removed resonator with new stainless mandrel bent tailpipe with 5" tip- And gave the perfect sound that I wanted. I noticed a difference in the exhaust tone, perfect Idle loudness and just the exact sound I wanted. I have heard a Similar ram with identical exhaust set up minus stock size tip, and the sound is noticably different.
