Flowmaster 9530452 Super 40 Series Muffler - Enhanced Performance with 3 In(C)/2.5 Out(D) Diameter Review

Arrived on time and the part fits. Installed the same day. Sounds fantastic on my 2014 Ram 1500 4x4. I would recommend it to anyone who wants great performance from a quality product!

Great sound! You'll hear a deeper hum coming from inside the cabin, but it's nowhere near loud enough to make a difference when listening to conversations or music. Gives you a deep, throaty sound when it's definitely audible from behind. Love it!

I hardly give 5 stars for the maximum of only 4. However I gave this one a month ago. I'm an electrician, not a mechanic. However, I found it very easy to install and sounds great. However, be aware of the size you may need for welding.

Very happy with the result. Really wakes up the truck without becoming obnoxious or ruining the interior experience. I can't think of any other mod in this price range (mine was $125 for a professional install) that I love as much as this silencer.

My previous aftermarket exhaust was a heartthrob. It sounded amazing. I could hear that muffler from the cockpit enough without being obnoxious. It also had no rumble. Unfortunately, after 3 years, the two exhaust flanges were completely rusted through. I switched to the FLOWMASTER Super 40 based on the many reviews I read about various silencers. The noise in the cockpit is almost zero, there is no rumble at any speed. I've had mufflers in the past that drove me and my wife crazy. The Super 40
