Enjoyed this one!
I must have had 40 series Flowmasters on my 79 vette as they definitely had more of the burble at idle. Seriously though, these mufflers are perfect for my Mustang. They are a little louder than stock and sound great above 3,000 RPM. Any louder and the neighbors would wonder who that 16 yr old boy is that moved in next door. I'm 57 yrs old and am enjoying my 2nd childhood. Power is good and the sound is not bad inside the car. You definitely know you don't have the stock mufflers anymore. Installation is a breeze and everything matched up perfectly. After this upgrade my SCT tuner made a subtle difference, however the car is fast.

Flowmasters Force 2-(2013 Mustang V6)
Looks Good,Great Sound. It's a headturner when I'm passing by people. Stage 3 did a big favor and price matched with another competitor and got it even for less with everything out the door.

Force II axle back
Pugh these on last weekend. Didn't really know what I was doing when I started but it was easy. Drivers side was more difficult and it helps to have someone help you hold it together when you tighten the clamps back on. In my case my 10 year old son sufficed. A rubber mallet and liberal amounts of wd40 helped get the chrome tips seated, looks and sounds awesome. Just the right increase in volume and they turn heads when you step on it. Sounds much better than even stock v8 and tons better than the ones that came on the car.

2013 Ford Mustang V-6
My wife loves the sound of her Pony now. Stock mufflers are too quiet for a flashy car like this. The Grabber Blue with the new sound turns many heads. Great price and they fit perfect. First one took a little time to get the old mufflers off but the second one was a breeze. This took about an hour to install both. I put the car on jack stands for more clearance.
