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.

"This muffler produces a great sound. Loud enough to sound cool without being obnoxious. Made my V6 Mustang sound just like a V8! I had a shop do the install so I can't commment on that aspect, but it only took them about 20 mins. I can feel the extra horsepower in the higher rpms--an extra 5 mph per gear (roughly). Haven't noticed a mileage increase yet. All said, a great pipe!"

Not an exact fit...

"After cutting off my old exhaust, I realized that the muffler sent was not an exact fit. On a 1993 F250 w/460 engine, you need a muffler with center inlet and outlet. I was sent a muffler with offset inlet and outlet. Not a big deal, I made it work, it was just a pain. Other than that, the quality is excellent. I immediately noticed a gain in power and increase in mpg. I recommend it to anyone, but if you have an old truck like mine, call them or check the part before you cut the old one off."

"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."

"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."

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."

"I have a few likes and dislikes about this exhaust system. Likes: Very easy to install, and it fit perfectly.The chrome tip is nice and simple, and just the right diameter, not too big. Being painted black isn't as nice as being polished, but it does hide well under the car so the tip stands out. I am not able to get hard evidence, but I think I have noticed a little better performance. It sounds good under hard acceleration, not winey or like a tin-can, like those stupid coffee-can mufflers kids are installing. Dislikes: The black paint had scratches all over the muffler and pipe when I opened the box, and it was packed nicely, so it looks to be scratched from factory. I wish the chrome tip didn't stick out as far as it does, maybe needs to be 2 inches shorter so it tucks up nicely with the bumper. The muffler has a slight drone at faster highway speeds, but not too bad. Im not sure I have been able to get any additional mileage with the system, but I may need more driving time to really tell."

"The instalation took about 3 hrs and went together very nice execpt the tip had to be tacked welded, the clamps work fine except the tip would not tighten firmly to the tail pipe, the sound was not what i wonted a little to low, A 40 series would have been nicer like the one i have on my other trucks and my sons mustang, if i could i would have had a 40 series more hefty sound, ive only droven it one week and see no gas saver , i did see a power increase on my other trucks and as long as i kept my foot out of throttle the gas milage goes up, it would be nice if they would exchange the 50 series for a 40 series i think it would improve my gas milage."

"Overall I like the Flowmaster Force II. I definitely notice the horsepower increase right about 2300 RPM and higher. Truck definitely sounds mean when you get into the throttle. I like it! I have just as much exhaust flow out each side of the dual exhaust now as I had out the original stock pipe. I drive short distances, so condensation is a problem for me ( the added heat helps dry things out. Great product! I'd buy it again!"

"I bought this system hoping to gain in gass mileage as well as performance. Install was easy to do. I am no mechanic but with a second set of hands things would have been easier but other than that the installationisa breeze. For those of you who don't know this I used PB Blaster to loosen the rusted bolts (Tremendous help). Overall I am very happy with my purchase and still waiting on the gas mileage gains. Initial driving seems to show I will save a gallon or 2 per mile. I would highly recommend flowmaster or autoanything for your car/truck. Shipping is super fast also. Ordered my system Friday and by Monday afternoon had it. Good job autoanything!!"
