Flowmaster 952546 Super Muffler Aggressive Review

As an automotive enthusiast, I recently upgraded my exhaust system with this aggressive super muffler and I must say it's a game changer. Based on my observations, it has greatly improved my car`s performance and produces a deep rumbling sound that turns heads on the street. The installation process is easy and the quality of the muffler is unparalleled. The only downside is that it's a bit louder than I anticipated, but that's a small price to pay for the amazing performance and quality…

I put two of these on a Chrysler 300 and they sounded good at idle and with the lid fully open. From 2000-4000 rpm it sounded terrible and was terribly loud both inside and out. It wasn't even a smooth transition in volume or pitch. That's why I switched to stock.
