Description

Get every pony of the famous Flowmaster Exhaust System experience without the neighbor-waking, music-stifling blare of their loudest pipes. Flowmaster Force II Exhaust Systems are aggressive when your foot's down and mellow at cruise with less interior resonance.

With a Flowmaster Force II Exhaust, you instantly feel a 5% - 10% boost in acceleration and passing power, plus up to a 2 mpg improvement in gas mileage—just like the feel of Flowmaster's renowned American Thunder Systems. The difference is in Flowmaster's quieter chambered muffler that mellows the muscular sound without reducing power.

Adding to the Force II package is a set of mandrel bent pipes custom-formed for your ride, plus all installation hardware, and even a stainless tip for most kits. Mounting it to your vehicle is easy—many systems can be bolted on at home in less than 1 hour. And, your Flowmaster Force II Exhaust System is backed by a 3-year warranty.

So Easy to install... Even a caveman can do it

"The system arrived within a day of ordering it. The toughest part of the install was getting the old system off. Would recommend a sawzall for the old pipes rather than struggle with old tail pipe. Working with another person made the install a breeze. Total job start to finish took less than three hours and that included Cold Air Intake system and Nerf Bars so my daughter could get in and out more easily. The flowmaster sound is subdued when you want it to be and bellows deeply when you need that extra power. Installed with a K&N Cold Air intake to help with the power during towing and fuel economy when not. Haven't had the chance to tow my daughter's 8,000 lb horse trailer yet, but with the increase in throttle response and power just cruising around town, I have to believe towing is going to be much improved. AutoAnything was a breeze to order from and one of the best websites to search for the parts that I needed. Wouldn't think of shopping anywhere else."

"I love the sound of this inexpensive but great quality exhaust system. I had it professionally installed on my Mustang and it has quite a mean sound as well as adds some horsepower. With this 50 series I can have the deep muscle car sound I wanted while not making the neighbors mad!"

"This is my second Cat-back system in 7 years. The other muffler rusted through. This system was spot on. Easy to install, easy to adjust. Took me longer to remove the old system that to install new one. Took about 2 hours, by myself in my shop with the truck on the ground."

""As Advertised", great sound on the outside, and quiet on the inside. Very easy to install on our 2008 F250 Super Duty V-8. Noticable horsepower increase. Probably half the weight of the OEM system, but still very well built, and looks cool too! 2 Clean Lee"

"Every went in real smooth with the exception tail pipe. I had to file the slit where it claps down because it would not clap down tight enough. Great tone which translate that the wife is pleased! I am noticing a gas improvement of 2 additional mpg. I did the install for the mpg improvement and it delivered. I also added Jet Power Control Module but it has not improved the mileage. Thinking of changing axle from 3.73 to 3.08."

"Installation was a breeze, as with everyone else the hardest part of the operation was removing the OEM system. The total time for me was 2 hours. Sounds great, I have not yet checked gas mileage nor power increase but hope to soon. Auto Anything was great the price was right and I received the system in 4 days. Unheard of for me. Thank you Auto Anything I will definately be a repeat buyer."

"Little louder than the Flowmaster on my 2000 F-150, but still rolls down the highway with less than a low rumble with my 2006. Took a trip through the mountains and looked at my average milage and it increased 2.5 MPG (staying out off the pedal/75MPH Cruise). Overall average around town/highway savings looks like 1.5 MPG. Sounds great, good rumble, sounds like a Ford! Paid an additional $45.00 to have seems and tips welded as recommended in instuctions, no big deal."
