                Not too loud, not too quiet. Just right.

                I replaced the stock muffler in my 2019 Ram 1500 Bighorn with a Flowmaster 50 Series Deltaflow muffler. What an improvement! A bit more volume without being obnoxious, which is just what I was hoping for. A bit more rumble than stock, but not enough for the neighbors to descend on me with torches and pitchforks. No highway drone either. Don't really know it's there while cruising until you push in the pedal. I've received compliments from several - Ram and non-Ram owners alike. Very Pleased.

                I had the muffler installed with the help of a local muffler shop in town. The sound is mean when you fire it up. It mellows out quickly as it goes through the gears I'll give it time, after reaching it's breaking point, it should have a different sound.

                Nice sound

                Was worried that it would be to loud but gives a nice mild sound to my little 2.2L motor. Seem to run smoother on open road with less up shift. Used stock pipes 2.25" in and 2.25" out

                Flowmaster 50 Series Muffler Swap, 2015 Silverado

                The only complaint I have is its not quite as loud as I was hoping, but then again had it been too loud I would have been far more disappointed. Since I wanted it welded in, I had it professionally installed. Took 30 minutes and felt like I got a good deal at $70. Nice tone on start up, barely noticeable drone when the AFM kicks in, smoother acceleration and better mpg but not sure by how much. Autoanything was awesome once again with two day delivery.

                Exactly what I expected

                Flowmaster mufflers have always been quality, but most often more than I wanted to spend. When I finally bit the bullet and bought one, it exceeded my expectations. It has a nice deep rumble that is not overly loud or offensive but about as loud as I want it to be. Sounds perfect for my straight 6 cylinder jeep.

                Welder fabricater

                The muffler arrived with one side scraped up which wasn't a concern for me. Installation was easy. Just make sure you have clearance where the tail pipe bends next to where the spare tire heat shield is located. I had to cut and reposition the rear hangar to move the pipe over about an inch. The 50 series is quiet and slightly louder then the stock muffler. I was told by the sales person that the 40 series was ubnoctously loud and I should get the 50 series. I should have gone with the 40.

                this is my second one of these. great build quality, can get a little drony if installed with no resonator on a 3.00" or larger pipe. and the stainless 409 version comes coated in something - not sure if ceramic paint or just high temp paint, but it looks MUCH better polished. great quality.

                This was the deep sound I was looking for. Definitely turns heads but doesn't annoy you on the highways. I get that rumble when I reached highway speeds and no drone. I'm very happy with my muffler. The wife likes it too, so that's a bonus.

                Flowmaster 50 Series Delta Flow Mufflers

                I bought these to replace the S-mufflers that came with my Stainless Works exhaust. They were fun just running around but much too loud for pulling a trailer for a 1000 miles up and down the mountains of WV. These fit the space perfectly and have a very good rumble with out overpowering the inside the cab. Wish I could have gotten them in stainless but they are well made and should last a long time. Just be aware that both inlet and outlet are ID. Great price, very pleased with results.

                Lamest muffler ever

                After install, it sounded exactly like the stock. I hated it. The truck had no growl what-so-ever. I replaced it with the 40 the next day! Why this one was more expensive, I'll never know. Don't waste your time, money, and sanity on a muffler that will give the same sound and performance as what's already on the truck! I love the 40, by the way! Now it sounds like a truck! Gives me goosebumps on each startup!

                Not for me.

                This is not for V6 trucks. I have a 2014 Ram 1500 V6. This muffler makes it sound as if my truck had a fart can on her. I know I annotated get the V8 sound. Not trying to pose as one. Just wanted a little louder than OEM. Had to have it welded. Midas told me after I had the welding job done by a cheap shop, they could not do anything to help the fart go away. So we are opting for a MagnaFlow muffler for my V6 instead. This 50 series might be good for V8, but not for V6.

                Good but.....

                Flowmaster is the only muffler I run on all of my vehicles. And when auto anything had a black Friday deal made them even better. However shipping took way to long and was shipped in the normal flowmaster box without any extra packaging. I'm lucky someone didn't steal it. I'm very upset about the rate of service. It's like it was just thrown out the door but couldn't have been since shipping took forever.

                Great Addition to my F150

                Nice deep tone. Cab noise not bad at all.

                got this muffler to replace a loud muffler I had on my 15 gmc canyon. I got this muffler cause I wanted quieter sound. Well that didn't work. This muffler is loud, was hoping for quieter. Mite have to go with a 70 series. Good product sounds good just too loud for me
