Anybody installed this on their 15-17 before with an H-pipe?

I didnt do that one. But on my old 2017 I had a Ford OEM GT350 rear valance and a Stainless works GT350 Catback. Fitment was perfect.

Unless you have the premium bumper (it’s a 2 piece bumper on the 2015-2017 cars), you’d have to get a whole new bumper. Non-premium 2015-2017 rear bumpers are one piece, there wouldn’t be a way to secure the valence to the bumper after you cut it up.

Otherwise, no reason it shouldn’t work with an H pipe (or x pipe).

Thanks guys, I do have a premium and I've seen where I would need to cut that one piece. But it doesn't look too terrifying.

I was more surprised at the price. That seems awfully less expensive than in the past plus Ford has a 15% discount that it allows me to apply. If I use my amex I'll get another 4% credit.

What are the rock drains? Forgive my GT350 ignorance lol

The holes on the bottom of the exhaust tips. Also there to allow any condensation from the exhaust to exit out of the tips

I know I saw it somewhere, so I asked Claude AI and voila!

"I found the Jay Leno's Garage video with the 2015 GT350R. That YouTube link from 2016 is almost certainly the one you're thinking of. Let me also pull up more detail about the "rock drains" specifically.


Found it! Here's the story — it's a great one.
The video you're thinking of is the 2015 Ford Mustang Shelby GT350R episode of Jay Leno's Garage (from February 2016), featuring Ford's Chief Performance Engineer Jamal Hameedi. You can find it on YouTube here:
Here's the explanation of the "rock drains":
The holes in the GT350's exhaust tips exist because of the tires. As Hameedi explained to Jay Leno, "The tires are so sticky that they take little pebbles, and they spit them up in the back of the fascia." Jalopnik
After a track session, the Mustang's hot tires become sticky like flypaper and pick up small pebbles and gravel from the road surface, flinging them toward the rear fascia and into the exhaust tips — which are cosmetic shrouds not fully connected to the actual exhaust pipes. Without drain holes, rocks would rattle around inside indefinitely. Jalopnik
The small holes are drilled into the bottoms of the exhaust tips specifically for rock drainage — and this is very much a real-world phenomenon. Owners have reported finding rocks and pebbles stuck all over the sticky Michelin Pilot Sport Cup 2 tires and inside the exhaust tips after a drive. Jalopnik
It's one of those wonderfully quirky engineering details — a simple solution to a very specific problem caused by having extremely grippy track tires on a street car."

It’s a great video, I go back and watch it frequently. Jamal is great and explains the car really well
