wrt to sound.......no Brad its not that we're getting old/fuddy duddy but like to hear ourselves think, enjoy our tunes and avoid being ticketed when exploring the speeds of our cars without announcing to the world we're doing so. My S4 would set off car alarms when deccelerating in the city with the X, no cats, small resonators and RMB set up.
almost every car I looked at thats driven any kinda distance and uses an X has a proper rear muffler........not a RMB..........Constantines muffler seems to fit the bill........I use a GT rear muffler on my S4 with the X, no cats, small resonators.
Not saying yours or others is not to loud with a RMB, and mine dose rap at WOT, but at cruising speed mine is fine and does not resonate loud in the car.
Deb and I can talk and hear each other fine at 80-90 mph so I don't know what is so different from my car to others.
Maybe I am defer then most
