Review on TOTALFLOW 646 Mini Muffler 409SS 4.5" Round Width 4" Body 6" Overall Length Inner Inlet-3.5" Outer Diameter Outlet by Julio Avikunthak

Revainrating 4 out of 5

Nice loud deep sound

I bought a 10in with 4in inlet, already had a straight pipe on my F-550. This took down the exhaust drone alot on the highway. Still really loud but made a big difference. After installing has nice deep sound.

Pros
  • The inner inlet of 3.5" ensures that the muffler seamlessly fits with your vehicle's exhaust system
Cons
  • The muffler may cause a check engine light error
