    • Louder than I thought
Noise is pretty loud, however I do here it inside more than I want. This is Better if you want it loud or a weekend car. Supper 44 will give the tone with less noise inside.

    • Picture 1 is deceiving, look at other pictures
This Flowmaster was everything I wanted with noise level, easy to install and perfect condition even after shipping. The 1 issue I had was that the first and main picture of this item shows a center outlet but wasn't that at all. I work long hours and thats why I order alot of my auto parts online to save time. It is totally my fault but cause the description says offset but I went by the pictures cause a muffler is universal. ... show more

    • For that hot rod thump…these are it.
As soon as I strapped these babies on my 84 Chevy suburban thunder and lightning shot out of each one of the tail pipes, in the distance I could hear the faint sound of taps playing on bugle…I knew this could only mean one thing, R.I.P. to the girl you used to see…her days are over…haha I coming for ya! ... show more

    • Good sounding muffler.
Bought this for a v6 ram 1500. Was worried it wasn’t going to sound good after install I couldn’t be more satisfied. Outside the truck has a good sound and it doesn’t drone in the cabin.

    • Sounds great! Deep rumble.
It does sound very nice. I have a 1992 Chevy van, a shorty. It’s cool. Exhaust sounds amazing.

Disappointed that they only lasted 4 years. This is the second set of flowmasters I've put on my 02 2500hd 8.1 and both have blown out in various places. These did sound amazing on the stock dual exhaust systems the 8.1 comes with! I do alot of heavy towing and plowing snow in the winter. But probably would buy again, but getting tired of welding new ones in! ... show more

    • Perfect fit for 2000 F250
Purchased this for my 2000 F250 with a V-10 it fit perfect you will need a couple feet of 3" pipe to connect completely to old pipe.. But its sounds amazing not too quiet not too loud.
