Remarkable Exhaust Upgrade!

I was truly impressed with the performance gained from this muffler upgrade. The sound was just right for my automotive preferences and the installation was a breeze. The only downside was the higher price point compared to other options on the market. Regardless, I highly recommend this product for all automotive enthusiasts looking to elevate their ride's performance and sound.

Pros
  • Improved exhaust sound
Cons
  • May exceed legal noise limits in some states

Good sound. Excellent quality.

As you know, this Flowmaster muffler has a distinctively deep, harsh sound that sets it apart from the competition. I installed it on a 95 Dodge Ram and everything was perfect. The build quality was high and I think it will outlive the truck.

Pros
  • Automotive
Cons
  • Clarity

sounds amazing. The truck is now spinning the wheels through second gear

I ordered it and received it in two days I took the saw to my factory 2015 Tundra SR 4x4 5.7. Place these on two tubes and center them on the tubes using makeshift spacers and weld. Used at the factory after the muffler hanger has been welded to the Flowmaster's dual outlets and everything has been properly hung and welded. Sounds amazing. The truck is now turning its wheels in second gear!

Pros
  • Muffler
Cons
  • Hard to tell
