Your cart is empty.This Force II axle-back exhaust system is constructed from 16-gauge mandrel-bent aluminized steel and includes a pair of specially designed 60 Series performance mufflers with the sound that goes hand in hand with the performance image of the car. The mufflers are finished off with large 4.00-inch polished stainless steel tips to fill out the exhaust cutouts in the rear valance for a muscular appearance that matches the sound. As a Force II system, it delivers a moderate exterior tone with moderate interior sound level that is suited to the enthusiast who wants their performance to be heard. Like all Flowmaster exhaust systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, the system includes all necessary parts and hardware for easy installation. Note: Fits both coupes and convertibles.

Not as loud as I though they would be!

The Force II axle back exhausts are little louder than stock and have no drone. With a stock h-pipe and a big cold air intake kit the exhaust is slightly louder than the intake at wide open accelerating to max rpm. I removed the American Thunder mufflers because they were louder than I wanted for early morning departure from my neighborhood. The Force II mufflers won't give you that problem. I gave them 4 stars because the exhaust tips won't center in the bumper cut outs, cosmetic only but for $500+ I would expect them to line up better.

For a 2010 Mustang GT: Just know that the hangers are such that the hanger mounts will need to be on the muffler hangers before sliding the mufflers onto the exhaust. Then attach the mounts to the frame with a closed end 13mm ratcheting wrench.

These mufflers provide a “like OEM” sound. They are not aggressive in sound. Just what I was looking for to maintain a low profile while out on the road.

Good fit, sounded perfect at beginning, still sounds good but has mellowed to a slightly lower tone. Good start up sound, almost silent at 70. Very little if any drone. No rasp. Stock system other than exhaust and CAI.

These will NOT fit if you have a trailer hitch installed. For some really odd reason flowmaster dropped the ball and decided to move the muffler forward about 4 inches from where the stock one sits. Which is where the trailer hitch sits.

Wanted some more rumble than the factory dual exhaust on my 2007 Mustang V6 4.0. I ordered this system and saved money with the Amazon coupon FLOSPRNG (good til 3-31-13). I priced this axle back out at $389.00 just about everywhere online. Amazon has them for $310.00 and with the coupon end cost $233.00. The sound is awesome! Nice rumble great through the gear changes and not to much interior drone. I cant complain and could not be happier. This is absolutely perfect. After a quick call to Flowmaster, I was informed that this system is specifically designed for the 05-09 Mustang V6. The end result One Happy Customer, and one happy mustang, it definitely turns heads

These should be what Ford uses as the stock Mustang muffler! Great muscle car sound. Cabin noise is only slightly louder at lower speeds (but it sounds great!) and no highway drone. I was a bit hesitant about ordering car parts from Amazon but they had the lowest price and delivery was very timely and the product was perfect. The installation wasn't too bad either. A little tight to get that bottom bolt in on the back hangers. The wife's little hands and an open end wrench helped out there. These things sound fantastic!
