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

Exhaust Silencer Review
I recently installed this exhaust silencer on my vehicle, and I’m really impressed with the difference it has made! The noise reduction is significant without sacrificing performance. My car now runs much quieter, especially at higher speeds, and I no longer have to worry about disturbing the neighbors or attracting unwanted attention. Installation was straightforward, and it fit perfectly on my exhaust system. The quality of the material feels durable, and it’s clear that it’s built to last. I also appreciate how it didn’t affect my engine's power output—it keeps things quiet while still maintaining the overall driving experience. One of the best features is how it manages to reduce noise without creating any rattles or unwanted vibrations. Plus, it doesn't add any extra weight, which was a concern I had before purchasing. Overall, this exhaust silencer is a great investment for anyone looking to cut down on noise while keeping their vehicle’s performance intact. Highly recommend!

2014 gmc 5.3l. I left the forward resonator and flex pipe, then went up to 3” and into the muffler. Then came out before the axle. Sounds great! Not super loud. Just a nice low growl. Will add pics when the exhaust tip comes in. Definitely recommend!!!

Super happy with this. Sounds awesome. Price is better than anywhere. My neighbors might not be as happy. But it's so much quieter than my old exhaust. Has that cool rumble and no drone on the hwy. My person can actually talk to me when I'm driving........(as if I'm listening lol.)

Put on my 07 ram (has cats, no resonators) and it sounds very very good . Minimal drone at cruise or at highway speeds but just a touch loud for my liking . I have used many different brands of mufflers, but this one put on a Hemi almost gives it a slight lope/chop at idle or cold start that is pretty impressive . Would recommend if you don't mind it being on the louder side, but what do you expect for a straight through muffler. definitely not as loud as a glass pack.
