The easiest most complete kit I've ever worked with. Done all the nice upgrades(o2 extensions MLS gaskets and band clamps) bolt on. Little room as far as clearance but look what you're putting on. I'd buy again. Purchased through another vendor(mont) as the official site was out of stock at the time. I cannot recommend this kit enough. It's so complete and nice.

Fits decent

Fits pretty good, driver side I had to shave down engine mount bolt. Passenger side close to the fire wall, you can try shifting engine over or some light messaging on header. Probably the best fitting header thats not over 2k or custom made. I would just use all the supplied header bolts. Some resuse any of the studs not worth the time to figure it out.

Great overall

It's a header swap, so it will be tight. I just completed header swap on a 2023 mustang gt "working on mid-pipe to rear axle now". Research shows passenger side is the hard side "it is". The problematic areas are header bolts, and how to access them "specifically the bottom row outer edge, and upper further towards the front". The passenger side motor mount top nut is also a pain to get to. overall header swap was long but no fitment issues.

Sound really good and fit right in

Extremely satisfied.

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).
