This Stainless Power longtube header kit features massive 1-7/8" diameter 16ga primary tubes to really let your Coyote engine breathe. The large primaries then lead down to a 3" slip fit collector and into 3" high flow catalytic lead pipes. These lead pipes have factory connections for a direct fit.
Stainless Power Quality
Stainless Power headers are some of the best fitting headers on the market. Fully constructed from CNC mandrel bent, 304 stainless steel tubing, these headers will handle anything you can throw at them. The flanges are 3/8" thick and TIG welded for strength and durability. Designed by Stainless Works, these headers are high quality and priced at a budget friendly price. Stainless Power headers are backed by a 24-month guarantee on material and workmanship.
-Installation of long tube headers will require custom tune to prevent damage to your vehicle. If you already have a custom tune on your Mustang, please consult with your tuner prior to installation and operating your Mustang.
They fit great, on the passenger side, take out the 4 studs close to the cabin and the header will go in easier.
Yes, I would recommend this item to a friend!

Great power and fit

Installation on driver side was smooth, was able to keep all studs in. Passenger side header had to have all studs come out to install, and put the header a little to close to an AC line for my taste so I wrapped my ac line in some foam insulation. Other than that it is an amazing product! Car sounds good.
