Flowmaster53070 70 Series Chambered Muffler

3 chambers keeps the drone out of the cab, but still has a great throaty sound when you get on the throttle.

Great muffler. Sounds good. Absolutely no complaints and would buy again.

I put this on my 95 F-150 with 302. I do a lot of highway hauling with this truck, so I didn't want to have a lot a drone. I put it with a vibrant ultra quiet resonator, high flow cat, and shorty headers. Overall I'm really happy with it. It isn't much loader than OEM, but has a subtle flowmaster rumble.

Had a Mbrp bolt on exhaust system installed but muffler was way to loud. Replaced the mbrp muffler with this 70 series flowmaster bolted right up. Very quiet and deep. I’m very satisfied with my purchase.

It says sounds little louder than stock muffler but its not , i have LSA engine with headers I installed this muffler it sound too much loud than the stock so i went back to stock muffler. Police will catch me for the noise..

I had heard that this muffler was a good muffler, but I am very impressed with its performance and the better gas mileage I am getting. I am a huge fan of Flow Master because I have the mufflers on my Mustang. I wanted the 70 series because I was looking for the performance but without the noise. And I have to say I am very happy both this purchase.

After contacting Amazon, they referred me to the manufacture who referred me back to Amazon who said that the return time had run out on the item.

Installed on a 02 f350 crew v10. Sounds good at idle and acceleration. Is quieter than the goodyear wranglers on vehicle cruising. No cab drone
