Great muffler, I love the deep rumble.
Sounds great on my truck. Really let's the engine breathe. Very well made and it has increased the torque and throttle response in my my old pickup. Only drawback is the drone in the cab however alot of that may be just my setup as I just put a turndown pipe 18 inches off the back of the muffler.

Sounds good but not too aggressive
Sounds good if you’re looking for a little louder than stock. Not too loud and no drone Just gives a deeper tone. Looks good also. I used it on a 95 Chevy dually with a 454 single 3 inch exhaust. At About $50 is a great price. Can’t buy stock for that anymore

Excellent product! 5.7L Hemi sounds fantastic with it!
Muffler sounds great! I had my truck essentially straight piped with the factory catalytic converters on. I couldn’t stand the droning in the cabin and was looking for an inexpensive but effective muffler. This muffler helped reduce the cabin noise significantly and the truck still sounds great. I would highly recommend this product!

Perfect exhaust for a great price!
Awesome exhaust for the price! It went straight from the delivery guys hand onto my 04' ram 1500 5.7. Sounds great!

Stainless steel Flow FX straight through muffler great quality and price!
The Flowmaster FX muffler is a great value especially for it being stainless steel I was able to install it with just 2 reducer pipe fittings and some welding and 2 pipe clamps it’s a nice looking muffler the sound isn’t obnoxiously loud it is mellow at idle on my 2002 Chevy Silverado with 5.3 and when you lean into the gas it has a good deep tone there is a slight drone when under light throttle but controllable
