I just bought a Z71 and it dosen't have cats or mufflers, with 2.5 in tips. It is loud as hell and I need to quiet it down. Idk, if I should just put some mufflers or just cats? I was looking at the Flomaster Super 40 dual inlet and dual outlet for it. IDK, how much it would quiet it down though. I can get the muffler for $100 or cats for probably $150, plus to get them welded on. What should I do, I want a nice sound and don't know if just a muffler would sound good or not. If you have just mufflers, would you post a video or give your opinion. Also, does anyone have the flowmaster super 40 dual inlet and outlet.
