Flowmaster Flow FX Chambered Muffler – 2.50” Offset In / 2.50” Offset Out – Moderate Sound – Stainless Steel – Affordable Performance for Modern Trucks, Muscle Cars & Daily Drivers (71236)

Sound GREAT. I have zero complaints with these. put together well, flanges weld nicely. great product and will be buying them again on future projects.

The media could not be loaded. I love the way it sounds, i had a hard time picking what muffler i wanted based on youtube videos and word of mouth, as i couldn't fully appreciate what different ones sounded like. But i am very satisfied that i chose the FlowFX, it sounds great, looks decent, and is great for the price. It actually made my truck get slightly better fuel mileage compared to the stock muffler, so i can assume it helped engine performance. It was a littler shorter than the stock muffler, but i also had a Y-pipe so it fit perfectly for my application. (Please ignore my shoddy welds lol, i used a flux core welder) I put this on my 03 Silverado 1500HD with the 6.0L LS, Stock.

I was after a bit more sound from my 2003 5.3L Tahoe when I purchased the FlowFX. After having this muffler on my truck for several months now I can say it's definitely louder but it wasn't quite the sound I was looking for. There's nothing wrong with it and this is actually a really nice sounding muffler if you're looking for a really smooth sounding exhaust. I would say this is mellower (if that's even a word) then most of the magnaflows I have heard. That being said the flowFX does sound fuller imo then other Flowmaster mufflers out there. Much less tin can sounding and more like a Magnaflow. I personally like my exhaust to have a little more of a throaty sound to it and this was just too bass heavy for me.The biggest down side by far is the presents of drone. After reading some reviews on here, there's a handful of people claiming that the drone isn't bad or is very tolerable but to each their own. I would say this is a solid 6/10 on the drone scale. It's not the worst drone I have heard but it's enough to bother the family on road trips. For this reason I will be removing it from the Tahoe and am going to replace it with something else.I don't fault the muffler for this at all as it's not really claiming to be drone free. The construction of the muffler is good and looks to be high quality. If you don't care about drone and are looking for a smooth and mellow sounding muffler this will do.

Why did you pick this product vs others?:Love it. Its like a better glass pack. Almost quieter than stock at idle. Loud and raspy at full throttle. Cruising at 80mph its nice and mellow. Pass someone and it sounds like you mean business. And this is side piped ahead of the rear wheel.

This muffler woke up my 2006 Land Cruiser that has a V8 in it. Makes the truck sound great without being overpowering. If you want to have a good sounding muffler without the serious loud drone at highway speeds, this is a good option. Price is right as well!

Great muffler sounds better than I thought it would AAAA++++

Sounds excellent

Looks good and sounds even better. I threw this on a 2014 Infiniti Q50 3.7L as part of the SCS exhaust from YouTuber Speed Culture Studios. It definitely ties it all in and has been going strong for 4 years.
