2011-17 Mustang BBK Full Length Headers - 1 3/4 Ceramic - 5.0 by BBK

So I bought these headers and I did not want to deal with the pain of installing them. This install is a beast and if you are not a competent mechanic...dont try this yourself. A quick tip however, is...if you're gonna do this yourself...go a step further and drop your k member, its not overly hard to do and while your k member is out, you can change your lower control arms, and maybe some cool polyurethane or heavy duty motor mounts, and it just gives you way more room to work and not mess anything up, just be prepared to get an alignment afterward, and have a substantial way to support your drivetrain (I used trailer jacks and blocks of wood), it took me 4 days of about 6 hours each day to finally get it all disassembled, installed, and reassembled. Now enough about the install and more about the product...these things are awesome, the power gains and sound are unbelievable. My stang tears up whatever pavement it's on, and sounds great doing it. I paired mine up with a bbk off road x pipe and 4 new O2 sensors (my car is a 2011 5.0 with about 56k miles on it, but I had been running an off road x and off road exhaust prior to this install, so my O2 sensors were impossible to remove from my old exhaust and were probably due for a change.) I'm going with 4 stars due to the difficult install, and lack of clear instructions with some of the hardware and studs that need to be removed from the engine. But overall I am very happy with this product!! I'll include some install pics!!

Recently installed these LT bbk headers with the mid-pipe and couldn't be happier. Great sound and instantly felt the difference in hp.

I bought this a few weeks ago. It's perfect.
