Review on Flowmaster 42543 2.5-Inch Inlet & Outlet 40 Series Muffler by Ken Perry
Good sound! Best Performing Parts & Accessories
I bought two 40 series for my 2015 F150 5.0L, headers and dual rear exhaust installed with them. The sound of the truck is very good, mostly loud, but sometimes turns into a quiet hum. When I step on the gas it sounds loud, although no complaints here.
Pros
- Satisfied so far
Cons
- Damaged
