Review on Flowmaster Super 44 409s Muffler (2.5 Inch Inlet/Outlet) by Daniel Oliver

Name: Flowmaster Super 44 409s Muffler (2.5 Inch Inlet/Outlet)
Item: Flowmaster Super 44 409s Muffler (2.5 Inch Inlet/Outlet)
Rating: 2

September 09, 2022

ineffective on mufflers

Slightly louder than stock muffler plus my gas mileage is down three mpg. Called Flowmaster tech support and got a response. I wish there were other reviews when I bought this but thought they were a reputable company.

Pros

Sturdy all-welded stainless steel body 409

Cons

Negative torque present
