🚗 Enhance Your Vehicle's Performance with Flowmaster 53072 3 In(C)/Out(O) 70 Series Muffler Bbii Review

I have installed 70 on several of my trucks and SUVs over the years. They sound great, not too loud (unless you can get it) and no hum. They're now made in China, but the Flowmaster still commands "Made in the USA" prices. isn't cool

I bought a 70's 3" Flowmaster for my 2004 Suburban 5.3 4x4, it sounds great but annoying cockpit hum around 2krpm and on the highway 2k is mostly cruising rpm and it's annoying and tiring on long trips, I take it off and go back to the factory muffler.

Quality is good, packaging is just right and delivery is on time. I run 2.5s in a full tail length 3 right to the end of the truck. There's still a harmonic hum, not as quiet as I was hoping, but all is well

This is my second Flowmaster muffler. You can't go wrong with it and it sounds great. Not loud at all, just a low rumble, just right. As for the chosen carrier of this package, the team members are confused. The box was broken, sealed with tape as if nothing happened. I know it's not the only package, it's every single one that this courier leaves at my door. For this reason four stars

2010 Silverado 5.3L, A/T, 4WD. Looking for more mileage and a little more traction. Didn't want a lot of noise. Installed Flomaster 70, K&N air filters and Mitchlin tires. After over 5000 miles I found the following: Revain: best price on muffler and air filter. Delivery was fast. Flowmaster 70: no increase in performance. No increase in mileage. Great sound - soft. No sound except at high power. K&N air filter: VERY LOUD when accelerating. Small increase in performance. Small gain in fuel…

I am very happy with this purchase. I had to replace the stock muffler in a suburban 2001 due to a leak a few years ago. It was then that I decided it would be a good idea to switch to a performance muffler. I've looked at both this and a similar Magnaflow. For some reason I originally got Magnaflow. It was intended for use with SUVs and had no resonance. At the end he was mumbling and echoing so internally that I handed him back. That doesn't mean it's bad relative to Magnaflow, it just didn't
