5.0 out of 5 stars It's a Flowmaster!
Reviewed in the United States on November 30, 2024
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!

The Flowmaster 3 In/3 Out Super 10 409s Muffler delivers a truly exhilarating exhaust note, adding a deep and aggressive tone to my truck. Crafted from durable 409 stainless steel, this muffler not only produces a powerful sound but also ensures long-lasting performance and resistance to corrosion. The three-chamber design enhances exhaust flow, providing a notable boost in horsepower and torque, making it an ideal choice for enthusiasts seeking both enhanced performance and an impressive auditory experience.

5.0 out of 5 stars The sound you're looking for!
Reviewed in the United States on March 4, 2015
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 )

5.0 out of 5 stars High quality
Reviewed in the United States on October 25, 2023
Awesome quality, made in the USA. Put a pair of 3 inch on my 1966 GTO with a built engine. Sounds very aggressive, loud and massive chop! Yes there is a drone. Yes it's loud. And yes I smile from ear to ear everytime I start it. Big V8 muscle car sound.
