BBK provides a high quality prefect fitting header for the 3.7L mustang. Nice midrange bump in power too if followed up with a performance tune from MPT. It also makes a more aggressive exhaust note which is nice for V6 guys.

These are nice headers for the price. The welds are ok, and the finish is decent. They look 100x better than the stock headers, and sound good with my Gibson cat back. These headers will offer more responsiveness in the lower RPMs, which is great for daily driving. Install was a pain, especially the driver's side. Be sure to research the tools needed if you plan to install these yourself.

Better low end torque, better sound, and they look great. Takes about 4 hours to install. You'll need jack stands, stock manifolds come off with deep well 1/2" socket and collectors need 15mm deep well. To install headers you'll want a flex head ratcheting 1/2 inch wrench and a 17mm deep well socket for new collector nuts. I also used a jack under the H pipe to keep it in place.

They were a real pain to install, it took 3 people about 4-5 hours. Halfway into it we notice one header had a hole. I absolutely knew I didn't want to remove them and send them back after 2 hours of work so I just left them and finished. I ended up taking my car to a muffler shop where they just barely touched it with a welding machine and it was good. Not sure how they come manufactured with a whole but other than that happy with the final product

The headers fit perfectly and look good on the car. It is a fairly straight forward installation, but requires some patience and a universal joint socket adapter is helpful for collector bolt installation. Only issue is the supplied lock washers were SAE and did not fit, so I purchased metric type from a hardware store. The headers look to be much better flowing than the stock exhaust manifolds and although I do not have ¼ mile times or dyno runs to prove it, the car does seem to pull harder.

First, this will not change the sound coming out the back. However, after a week or two, they seem to "break in" and there is a nice deep growl from up front (especially when you get on it!). Second, they do give more torque. I can light my tires up pretty much at will and there is certainly more get up and go. Again, don't go in thinking it will turn a V6 into a V8, but I guarantee they will think twice at the light!

Although the instructions warn about the lower rear leaving the passenger side loss until accessing the lower rear nut,access to turn the nut was still a problem. Had the layout of the pipes allowed about another 1/8" from the end of the engine stud and the header pipe, I would not have had to devise my own special tool.
