2011-17 Ford Mustang BBK Shorty Headers Silver Ceramic Coated V6 - S197 by BBK

I ordered these about a week ago for my 2012 3.7L Mustang. I got them in just a couple of days - super fast! I was surprised at the increased mid-range and high end improvements in performance. I had just previously installed the BBK 73mm throttle body, which had improved my low end torque, I am very pleased.

Installation: read the instructions. The next-to-last stud/nut on the passenger side needs to get started before you tighten anything down on that side. I used a half-inch ratcheting combination wrench and a very long (2ft) screwdriver to keep the wrench engaged, for most of the nuts. The fit and finish is great. Yes, I do recommend these, and this is a great place to get them - my thanks to Jay Walling.

I purchased the Ceramic coated BBK Shorty Headers for my low mileage 2012 base coupe with the 3.7 V6 engine. My mechanic installed them in about 4 hours; having a lift made all the difference. He reported that installation was straight forward and a breeze on the driver's side, but a little more laborious on the passenger side. Be sure to get all header-to-engine nuts started before tightening any of them all the way up. He suggested working each of the nuts in a little at a time to avoid any problems.
Even with the rest of the exhaust system being bone-stock, there was a deeper rumble when I start the engine. I can only imagine how much better it will sound with after market axle-back or cat-back mufflers on it. That will be the next project. Until then, I will enjoy the great looks when I raise the hood and the much deeper exhaust note. Seat-of-the-pants experience tells me there is a little more low-end grunt and the engine is winding out much more freely. What a great addition to any 3.7 V6.

BBK has had a good reputation for many years. What made this purchase even better was going through LMR for the purchase. These guys and their shipping is second to none.
I was jacked around for 2 weeks for the same item elsewhere before I canceled and ordered them from LMR. I ordered them on Monday and was at my door that Friday....

The shorty headers were in great shape and I highly recommend the ceramic coating. Like many have said the headers do tone down the sound a bit from the stock manifold. Don't know why but they do. The trade off is low end grunt, I can tell the increase in bottom end from take off to cruising at highway speed. It takes less pedal to maintain your speed which I'm sure over time I'll see and increase in MPG.

Don't get me wrong, when you step on the gas they let you know they are there. I run Borla tour AB and the combination sounds deeper than it was before. If you're getting these for more sound don't bother, if you wanna dress up the motor and gain bottom end I recommend these for sure.

I'm an old fart and it took me 5 hours by myself to install them. A good part of that time was cutting the manifold to the exhaust pipe studs in half since they unscrewed from the manifold and was dangling in the flange. It takes very few tools to complete the job. Number one tool is a ratcheting 13mm box wrench...
It wasn't necessary to remove the starter like many others have said. Just more work than needed...
