Review on πŸš— Flowmaster 52571 70 Series Muffler - 2.50 Offset IN / 2.50 Center OUT - Mild Sound, Black: Optimize Your Vehicle's Performance with Flowmaster's Superior Exhaust System by Jerome Pritchard

Revainrating 5 out of 5

Flowmaster 70 Series on Ford Econoline 4.6L V8

Installed this muffler for better flow on a 2010 Ford e150 Econoline Van with 4.6L V8. It has a nice deep, low rumble at idle and a smooth tone when accelerating. There's a slight rumble in the cabin but it's not annoying when driving and I think it applies to any aftermarket exhaust system. I've been using floaters for many years. I also have 50HD on my other truck.

Pros
  • Easy Install
Cons
  • Expensive
