Flowmaster 42543 - Flowmaster Muffler 40 Series 2.50 Offset IN / 2.50 Offset OUT - Aggressive Sound.
The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.
This two chamber design incorporates Flowmasters patented 'Delta Flow' technology. The 'Delta' deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle. Sounds great on late model performance cars with catalytic converters. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability.

I have the 1lt (base vette non npp exhaust). Installed this part yesterday evening with a friend. There is a video on youtube that was for another manufacturers larger system that helped with removal of the bumper and factory exhaust. On the way to work got a check engine light. Flowmaster is aware of the issue and is going to have me speak with R&D tomorrow!
This part only!
Flowmaster 2011-12 Mustang 3.7L V6 Force II Axle-Back Exhaust 1 notch above stock

I watched countless YouTube vids of axle backs for my car. Let me say they're essentially useless! Based on the videos I had my heart set on a ford racing or borla touring exhaust. They seemed to have the deep sound I was looking for without being obnoxiously loud. I was avoiding the flowmaster setup based on a few videos that made it sound too high-end and not rumbly. I was set to spend 700 on the borlas but stumbled on a vid of the flowmasters that sounded good. So I decided to risk it to save some dough. I'm not disappointed. I put them on in under an hour. The fit is stellar. So easy to line up in the valence, looks great! If you're looking for a crazy loud system this is NOT for you. It's not much louder than stock, but has a much beefier sound. There's no drone in the cabin unless you really are looking for it. At cruising speeds with the radio on you can't hear the exhaust. Dip your toes into the gas tank and it roars pretty good, but again nothing obnoxious. I think it's perfect for a daily driver.
