Ha, ha!
I was just about to pm you and Martin to suggest you guys should seriously consider this mod.
Best low buck mod you can do to an S550 Coyote.

Are you reading this Martin?
About 10 free hp, lose 30 lbs of weight, and no tune required.

I have a similar H pipe on my ‘15.

Simple cut, remove resonator and insert this H pipe instead.
Front part reuses factory clamps.
Rear part uses clamps shown in picture.

And, I’m sure this fits the 2024-25 too.
The exhaust is all the same under there and it’s the same chassis underneath the sheet metal.

Haha yup put it on a couple years ago. Definitely noticed a difference in throttle response. Well worth the price.

I am tempted, but don’t want to mess with it too much while it is still under warranty. It goes into the dealer for an oil change and MVI next week. If it would fit the 2010, I would likely be a taker.

I personally wouldn’t be worried about that.
Exhaust on these cars never breaks or has issues.

But if you like the mod and want absolute piece of mind for your warranty, you can by a very similar piece from Ford Performance from your dealer, have them install it and you warranty is protected.

It will be an X pipe instead of an H pipe but exact same result and installation.
No difference in performance. Asterix here*.
Only sound will be slightly different.
H pipe is more baritone or deeper.
X pipe slightly less baritone or a bit raspier.
Very subtle difference. If one didn’t know what is on which car, it would be hard to tell to the unfamiliar ear.

* Ok, there could be a very slight difference in performance.
To find out, you’d have to install the two pipes back to back on same car on same day and do back to back dyno runs with each to get results.
If there is any difference it will be very small.
Half a hp, 1 or 1.5 hp, maybe…
It’s negligible.
The most noticeable difference is in the sound differences between the two.
Has to be same car because any difference is within tolerance between different engines.
Has to be same day because difference could be attributed to air temp and/or humidity between days.

Here’s a pic from the 2020 Ford Performance catalog.
Their description says replace H pipe but that is a misprint left over from S197 generation.
They should say resonator.
No S550 or S650 were or are being built with H pipes. They all have a resonator.

We know many people read this forum without leaving any signs behind.
For those reading who are not so familiar with these cars, see bellow pic.

Look inside the white cardboard box on the floor.
You see there a rectangular shaped metal box with 2 round pipes sticking out.
This is the resonator. It’s larger than it looks there. It’s like a suitcase size.
Its purpose is to eliminate certain sound waves in the exhaust note for optimum interior cabin comfort.
But it is fairly heavy and it restricts exhaust flow.
This is why replacing it drops roughly 30 lbs of weight and allows the engine to breathe more freely, adding up to 10 hp.
And, as mentioned and demonstrated above, most gear heads prefer the sound that results after.

I agree with Marc and the Asterix is the HP conversation,
I agree if you change the older stock exhausts
with H you get better sound no HP performance, so they say.
they say with X because of flow you get 1-1.5 as Marc, said.

Some say the newer cars with resonators are more restrictive, so
elminating it gives you even more performance, as much as 1-2%
now again this is arguable and maybe you get a bit more. who knows.

But sound is far better, it will free up exhaust and engine will respond a bit better
and anything you can do to lower wieght, is a Plus Plus Plus.

Anyone thinking of this, even if not today, should buy this and hang in garage, your not getting
a better deal and with pony express, likely cost you a coffee and conversation,
best shipping in the Maritimes :)
