Sound really good and fit right in
According to my guy at the performance shop, everything fit well. He had to move the motor a hair in order for the headers to not rub otherwise he would’ve had to bang them in. All the bolts and hardware were perfect. He only had to tweak the x pipe a bit to be able to reach the borla catback I already had on the car. (2018 Mustang GT).
I had got these headers installed onto my car 3 weeks ago Great fitment is what my shop told me everything fit well. The only thing I would recommend is using oem gaskets and re-use stock bolts other than that the o2 extensions worked perfectly and would 10 out of 10 recommend these headers to anyone.
Absolutely Amazing for the price. No issues with fitment after installing 4 sets for customers ! Only issue i had was the bolts were the incorrect size but after emailing customer service , this issue has been resolved ! Now speed engineering needs to make a set for 11-14 coyotes as well !
Put them on 3 weeks ago and honestly love them. The clearance on the passenger side frame leaves some to be desired. I would personally test fit the pass side, and then dent the header in on that side just to be safe. It doesn’t touch, but the clearance is about 1/4” after I shifted the motor over a bit. Make sure to address the ac line bracket before you install the passenger side. The exhaust clamps for the exhaust are kind of a pain in the a**. Use a big impact. Im getting mine welded cuz I don’t like them. Other than those minor issues, i would 110% buy these again. $693 shipped. Quality is decent, idk how thick the expensive headers are, but these are about the same quality as the BBK headers on my 3.7 mustang. Came with o2 extensions, hardware, gaskets (dont use them, use only OEM gaskets), AND a sticker 😃 Roush axlebacks sound HORRIBLE with this setup though. And it is LOUD. I installed 12” Vibrant Bottle resonators to tone it down. It was almost enough to make them work. I would have gone with the 18” if i did it again.
