Yes have cats. Exhaust isn't to loud. Drone sound inside is what I want to fix.OP are you currently running cats?
I recently got some high flow cats after running catless for a while. Truck drives better and def isn't as loud. Different mufflers might change the tone but its still going to be loud as shit imo. I've heard good things about the kooks green cats, expensive but work well
I have a few projects in line first. Going to put it on lift and see if I can run some full size mufflers.
