as always that great flow master quality and sound. this product is really reasonable priced for the quality of sound it produces. i put this on my 21 GMC sierra with the 5.3 and it was not disappointing.

Sounds fantastic nice strong build. Functions like any muffler of its type should perfect fit highly recommend

Put these on a straight piped 5.7 Grand Cherokee. Sound awesome and gives her some rumble. Built nice and look good. Does drone a bit but to be expected. Perfect size I was lookin for. Watch the vid lol

Love the sound of this thing.

What more of a review do ya need other than the name Flowmaster?! The name is synonymous with quality, durability, dependability, performance, sexy and LOUD AF!! This one has a very loud cold start and @mid to high rpm but reasonable at idle and low rpm. You might only drive your neighbors nuts at the cold start for 5 minutes but it calms down as it warms. It's a Flowmaster so no worries about fit or quality. You get what the business has bled for, amazing performance! Best bang for your buck! No red woodpeckers can match the sound of a 2 chamber 10 series! Also I side exited my 2011 Silverado with a hole made 3" catback using this 3" single in 3" single out FM 10 series. Oh boy does it sound great! And stickers of course are on the truck and toolbox!

Over the years I have tried many exhaust brands out there and always come back to Flowmaster. I like the traditional "flowmaster sound", deep and aggressive so my favorite has always been the original 40 series. I tried a 10 series for the first time last year on my Dakota R/T and was impressed. This time the application was for my 03 Suburban 5.3 with cats. I heard an identical truck with super 40 and no cats and loved the sound and at first wanted to do the same but instead decided to keep the cats and install a 3 inch (in and out center/center) 10 series and WOW ! I absolutely made the right choice ! Of my many vehicles I can say this is my favorite exhaust set up ! Very deep aggressive tone and very noticeable inside the truck but not so loud that you can't hold a conversation and the sound is GREAT! If you are looking for the very best of the iconic "Flowmaster sound" and are torn between 40, super 40, super 44 or 10, I ASSURE you from someone with years of exhaust and Flowmaster trials the 10 series is what you want! And it's not obnoxious in its sound level . It is definitely loud but even my fiancé loves it and loves driving it. If you have a similar truck I also suggest the Spectre cold air intake kit. It's the best $150 you'll spend and the two go well together . Your truck will exhale freely with the 10 series and should be made to inhale just as freely . Both of these together made a VERY noticeable HD gain , increased throttle response and even noticeable MPG increase! (Yes even a Suburban!). And the CAI actually does make the exhaust note slightly deeper. Stop reading reviews and watching youtube videos and get it right now ! You will not be disappointed (speaking for V8 applications )

I was looking for a little more aggressive sound from my current exhaust and muffler. My truck, Silverado with 5.3L, initially had a “turbine” muffler on it. Previous installation and workmanship was poor and it was beginning to rust and had a hole. Decided to go with this Flowmaster Muffler. Very little difference in sound. Does sound better, but with as much restriction as they put on trucks nowadays, it limits the overall sound. Thought of deleting a Cat, but decided against it. Overall I am happy with the finished sound it does produce.

Loud enough to raise the dead

Been running Magnaflow since new(2020 Classic 1500 5.7 ram hemi) I’m going to say the Magnaflow 3” in 2.5” out duals sounded clean, definitely an exhaust that you’d want if your not into more gnarly sound, I liked it. BUT, this series 10 on the same truck is night and day! The growl at even mid throttle is to die for. Open her wide up and watch everyone look. Hiway cruise she purrs and zero drone. Slightly louder in cab then Magnaflow, nothing serious. At idle it’s slightly meaner as well. But gawd, that 1-2 gear shift punch at 50% or more throttle off a light is so deadly. 2 thumbs up here! If you like the muscle car growl this is the muffler for you! Side note, if you have the muffler back kit from Magnaflow, you’ll need a 24” 3” pipe to extend to this unit, I only had a 18” so I had to do some finesse welding for that with old pipe, and the 2.5” outlet is to ID and so were the original magna tail pipes, I had to cut off the old muffler and weld in some that were 2.5” OD so I could clamp it.

Quality isnt cheap, you gotta pay for the good stuff and this product is absolutely amazing. Id give it a 50 out of 10. Amazing quality product and sounds incredible too. If i could id give it 10 starts and not 5

Mega producto!!! Superó mis expectativas y lo recomiendo al 1000% Lo instalé en mi Kia Sportage GTLine 2017 y suena increíble. Si buscas un sonido deportivo y te gusta pasar por túneles para escuchar ese sonido como carro de carreras no lo pienses más!!! Esta es la eleccion correcta

These sound real nice on the 6.1 Hemi

Used on a turbo 4 cylinder 90's Volvo. Compared to running an open 3" downpipe it reduced the rasp and kills the drone at cruising speeds. Still aggressive at full throttle.
