Flowmaster 843015 3 In(C)/3 Out(C) Super 10 409s Muffler

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

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

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.

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 )
