Description:

The Flowmaster Exhaust System delivers more than a little sound and power – enjoy impressive horsepower gains, a handy boost in MPG, and the most famous exhaust tone in the automotive world. Not to mention, each Flowmaster Exhaust System is custom-bent from aluminized or stainless steel to fit your specific year, make and model.

Flowmaster has a wide range of different systems for you to choose from. If you want an all-out, loud exhaust system, go with the American Thunder. The Outlaw Series is an aggressive, race-oriented system and almost as loud. The FlowFX series has all that Flowmaster performance with a moderate tone. Sport compacts, imports and Euro machines sound off with the dBX Series, and, for wicked performance with a mild tone, the Flowmaster Force II System is best. Have your pick of single, dual, side and rear exits (depending on the model). Each kit is powered by performance mufflers and comes with all the parts you need for a quick install.

Your Flowmaster Exhaust System is backed by different warranties, depending on the materials used – for aluminized steel, you’re looking at a 3-year warranty, and for stainless steel, there’s a limited lifetime warranty.

2017 Flowmaster Exhaust

The Exhaust looks good and sounds great on the car. As far as installation I had it installed by a muffler shop because I wanted it welded on but due to the placement of the NPP controls on the driver side couldn't move the tips as far back as I would have liked. As it was had to cut a small portion of the bottom of the bumper to get it even with the bumper.

Not what I'd hoped for, but worth it nonetheless

While the kit is aesthetically pleasing, 100% stainless (thus it'll last forever), and relatively easy to assemble (a second set of hands made it soooo much easier), it's not quite what I'd expected from Flowmaster. I do wish it was a little louder. It sounds great, don't get me wrong, but not as great as their 40 series. I'll probably weld in a 40.. Too bad that wasn't an option at purchase. 9/10 from me.

Very easy install and sound.

Install was super easy compared to my Chevy. The only thing is that the driver's side tip is lower than the passenger side giving it an uneven look. Other then that it is a great system and I can feel the difference.

Awesome sound for a V6!!!

Removal was tougher than expected, however install was easy! Only issue I am seeing and having is the passenger side pipe (last two sections near spare tire) does not have a hanger to support like the drivers side does. After install the pipe worked its way down about an inch lower. I readjusted and re-tightened. Will see if it holds. Would recommend Flowmaster include a welded support similar to the drivers side.

Great sound

Had force II mufflers installed on my 2012 mustang V6. Really love the rumble and tone of these mufflers. Sounds a little more like a V8 though it's not. Overall i am very pleased with the force II system.

Great sound and very easy install.

Completely changed the sound of my 2015 challenger. Took only about 15-20 minutes to install(did have a lift to use thanks to my neighbors though). Would recommend this exhaust system to anyone.

AGGRESSIVE!!

The worst part is taking the old exhaust out. Sounds great at low RPMs but settles down enough so you can hear the radio on the freeway. Definitely a good decision.

Nice sound

Exhaust produces a very nice sound. Unfortunately it is quite a bit louder inside my cab than I expected. Looking at ways to dampen the sound currently, when pulling anything you cannot hear anything and the Mrs's isn't to pleased with that. Much louder than other moderate exhausts I have had in the past.

Cheap, simple, not obnoxious

Was easy to install, just cut the factory one off so I didn't have to drop the subframeon my 2012 focus hatch. Not too loud but the perfect low key sound. High quality clamps and piping, would recommend.
