Resonators and nufflers

Removing the resonators will not make you car more powerful, just louder. Get a decent cat back system for it. Check this place and listen to some sound clips. My son installed the resonator delete kit on his 2016 R/T. Made it sound pretty good, however, a true axle back with performance mufflers would have sounded even better.
