  • Very good value/ sound for the money.
I puchased this muffler as I wanted the stock exhaust to be louder (95 Tahoe 5.7l). Seems to fit the bill. I have the stock tail pipe (2 3/4") on the output of the muffler and it sounds nice. The old muffler was comming apart and I figured why replace with stock, this put it loud enough to please me and quiet enough to please my wife. The muffler with a 1' section of 3" was pretty loud in the cab, that is why I kept the stock tailpipe..... ... show more

The media could not be loaded. Classic muscle car sound! Fit and finish are excellent and made in USA! I was running Borla Pro XS’s on my Buick 455. They sounded fantastic while you were driving or accelerating but idle, just kinda sounded bland. These Flows are exactly the sound I was looking for. I listened to hours of clips on YouTube trying to pick one. From Magnaflow, Dynomax, Black Widow, etc... Get these, you’ll love them ... show more
