Description
More Horsepower And Torque. Improve the performance of your 5.0L Coyote powered Mustang throughout the entire RPM range with a Stainless Works Long Tube Header and Off-Road Shorty X-Pipe combo kit from AmericanMuscle. This Stainless Works Header and X-pipe kit will greatly improve your 5.0L Mustangs exhaust flow over the restrictive stock factory manifolds and mid-pipe to significantly increase your Pony's horsepower and torque.

Superior Construction. Manufactured from 1-7/8" mandrel bent 304 stainless steel tubing for superior airflow, Stainless Works Long Tube Exhaust Headers are TIG welded and feature a one piece 3/8" thick header flange for added strength and optimal leak-free performance.

Race Car Growl. The included Stainless Works 3" diameter 304 stainless steel off-road X-pipe not only improves exhaust flow to increase power, but it also adds a crisp raspy, race car growl to the sound of your Mustangs exhaust with its modern merged "X" crossover design.

Recommended Upgrade. To realize the full power potential that this Long Tube Header and Off-Road Shorty X-Pipe combo kit has to offer, AmericanMuscle highly recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. This Stainless Works Long Tube Header and Off-Road X-pipe combo kit is specifically designed to fit the 2011 to 2014 GT Mustangs equipped with the 32-valve DOHC coyote 5.0L V8 engine.

    loud and proud!!!

    After a long time of research I finally bit the bullet and bought some headers I decided to go with stainless works because I couldn't find anything negative on them and now I see why. Right out of the box the headers and pipes were In excellent condition with perfect welds stamped with the sw badge. I decided to have a local shop do the install because of time and its my daily. The shop installed the headers in a day (about 10 hours) and charged me 790 after taxes which seems to be the price for reputable good quality shops. I asked the tech who installed them if they caused him any trouble and he said it was a factory fit with no issues at all, he said you get what you pay for and these were great quality. I have the roush axle backs also and no resonators and man is it loud! Not the bad kind of loud though, IF you can stay out of the throttle you can keep it quiet (below 2500 rpms) but who wants to do that?! When you hit the throttle it screams and heads turn. I've received numerous compliments from people every day I take it out. As far as performance goes you can definitely feel gains. I have other bolt one as well and a SCT tuner with tunes from Bama. The headers added that extra power I needed to be satisfied for a while, I recommend anyone who likes a loud mustang that will pack a punch to invest in these they are worth every penny. Remember you get what you pay for these are worth spending the extra money for the quality fitment and performance.

    Excellent headers

    Out of the box excellent good looking headers little pricey but u get wht u paid for for installation took about 4 hours on a lift driver side was done in about 1 hour passenger side took longer cause of the first bolt was a pain to get to. But once we got it we cruise on the installation. Fitment was perfect and clean no issues and the sound is excellent I got with an off road x pipe I love it even more now. Shipping was extremely fast for such a big item I got in 2 days .

    Awesome product! Good fit, perfect sound, great power

    These installed like a breeze compared to other long tube headers, they sound amazing and it is definitely a noticeable power increase. Can't wait to strap the car to the dyno now!
