SHIPPING TO INSTALLATION PROCESSIONALS

  • It could be advantageous to ship directly to a professional installer instead of your home address. Just keep in mind, a signature is required for delivery, freight companies cannot promise delivery within business hours, and shipping damages should be reported upon delivery. If you're okay taking on the risks associated, we can happily send it to the address of your choice. If you go this route, please tell us if the delivery address will have a loading dock; otherwise a liftgate will be provided.

Overall a solid purchase

The inlet side came bent and damaged so that was disappointing but I have exhaust tools here so I was able to out it back in round with not much extra effort the sound is much better, does get a little droney but not bad, the quality for where the hangers go could be a bit better. Over all very happy with my purchase and even noticed increased fuel mileage as well with a better sounding truck.

Smaller than expected, and was just thrown into the gift box for me too arrange for presentation.
Easy install, and sounds very agressive

The hardest part was wrestling the exhaust pipes out of the hangers and factory muffler. Once that’s done, the Flowmaster can be installed in maybe 10 minutes or less. Goes back together very easy. I think it sounds very loud. If you don’t want loud, you should try FlowFX by Flowmaster

The HEMI came to life!

Excellent direct fit bolt on for a 2020 RAM classic 5.7. Finally the HEMI sounds like it should have from the factory. Deep, rich muscle tone... 5 stars!

Money well spent.

Flowmaster lives up to its name. Producing a great rich deep growl to my Ram Hemi.
One thing I appreciate is that it is not overly loud and annoying. It gave me the sound that I was trying to achieve…

Easy installation, great sound.

The only downside was that 2 of the opening were a bit dented. I had to pound them back into round so I could install it and not have any leaks. I assume it was from shipping as there wasn't much packing material. It was direct fit and easy to put in. I'd recommend soaking all the original hangers in penetrating oil and let it sit a bit before installation. Good sound, but not over the top loud with stock resonators still installed.
