🚗 Flowmaster 53070 3 Inch Inlet/Outlet 70 Series Muffler Bbii Review

Well built, excellent finish. I have been a welder for 40 years and am very impressed with the high quality of workmanship. Installed on a Ford F-350 460 pickup truck with a 1989 petrol engine. Very pleasant sound and low flow resistance.

I installed this on my 95 F-150 with 302. I do a lot of highway driving with this truck, so I didn't want to have a lot of drones. . I installed it with a vibrating ultra-quiet resonator, high-current coil, and short collectors. Overall I'm very happy with it. It's no longer bootloader than an OEM, but it does have a subtle Flowmaster drone.

Perfect sound and performance for the F150. Ideal for motorway journeys and everyday use. Not exactly the sound of other models, a bit more muffled, but it's a great combination with the cool Roush air intake. Combined, performance and sound feel close to a slightly underpowered Raptor.

I've heard this muffler is a good muffler but I'm very impressed with its performance and the best fuel economy I'm getting. I'm a big fan of the Flow Master because I have mufflers on my Mustang. I wanted the 70 series because I was looking for performance but not noise. And I must say that I am very satisfied with this purchase.

Insanely fast shipping first. Second, this is exactly what I was looking for. I have a 2003 Ford Expedition 4.6L, we always do expeditions on family trips, and I tow the boat with it on the weekends, so I need something that isn't going to be overwhelming but gives me the performance I need. On the Big Block 70 series, I got a very low rumble and very little self-noise (a very, very slight hum from around 50-80, nothing that music or climate controls couldn't drown out at the lowest settings)…
