  1. Sunny –

    Talk about the sound. The sound is amazing and really awakes the neighbors. he looks is good too.

  2. Garsone –

    Love the sound of the Flowmaster exhaust. Perfect fit. Easy to install. Has that awesome deep throaty sound.

  3. LocalGuy –

    Got this and paid to get it installed. Definitely worth the buy as you get a nice sound that isn’t overpowered. Worth the purchase

  4. Ron –

    This kit was pretty easy to install. The hardest part was getting the chrome tips aligned to my satisfaction. Only other issue is that this system is louder than I would like. The tone is fine but around 60 mph. It has a dull roar that makes me want to go faster or slower to stop this soundtrack.

    Let me star with just saying “mhmm that works”. Installed this system by myself in less than 4 hrs. As long as you follow the directions “exactly” it’s quite easy. On another note though, the image is not exactly what you get. This system is indeed full stainless but it’s unpolished, and the muffler is painted black not polished like picture shows. But don’t let that detour you. It’s still worth the money. A bit of buffing will make it shine just like the tips that come with it. Just wish they were the 3 inch tips and not 2.

    Easy install… Louder than expected and took a bit to adjust. Easier with 2 people but can be done by yourself, just takes more time to adjust

  7. DaleM –

    The hardest part was to take off the factory system. The exhaust fit well with the exception of the inlet hanger. It would not mount into the factory mount. Overall I am very pleased with the change. Not as loud as I expected, but I am happy with it. Definite difference in my engine performance.

  8. MichaelS –

    Everything fit just as advertised no problem installing hardest part was removing the original factory system

  9. CaptainsReview –

    I ordered the Flowmaster American Thunder dual Exhaust system and had it professionally installed straight out the back. It is Awesome! I Love the sound and it increased my horsepower slightly as well. I recommend this to anyone looking for an affordable upgrade for their exhaust system. The exhaust looks Great as well with those Flowmaster tips!

    Haven’t heard it from the outside, but it’s louder in the cab than I expected. Sounds good on start up from outside. The 2.75” clamp that was welded on the hanger was a treat to get over the 3” inlet pipe. Removal of the stock exhaust and install of this was not bad. System seems well made, shipping was fast, the delivery almost beat the confirmation email
