Review on 🚗 Flowmaster 524553 2.25 (Diameter) Inlet/3 (Diameter) Outlet 50 Series Muffler for SUVs/Performance Vehicles by Brandon Wong

Cold start noticeable. After that I didn't feel any difference at idle but when I accelerate I have a growl and a roar There is a slight rumble when cruising around 1600rpm but this is acceptable (I have sensitive ears) and once it hits 2kU it goes away Everything is so great!
