[egotistical4198]

Hello all, I’m curious on what size headers I would benefit most from. For reference, my future build list is as follows…
2024 Mustang Dark Horse with Handling Package, 10 speed auto

1. Borla ATAK exhaust system
2. FP Stage 1 Whipple SC
3. FP Driver/Passenger catch cans
4. FP axle shafts
5. Whipple open air box kit

Thank you in advance!

I would do Stage 2 but I wanna keep the 3yr/36k mile warranty

You can't do headers then.

Oof…thank you for that!

Even with the Magnusson-Moss act too? Won’t they have burden of proof in order to slam me with a warranty void?

I wouldn't want to find out.

Funny thing is you will likely cook the stock cats and have to get warrantied for those...I really would not worry about the engine and just go stage 2 w/headers... I'd worry about the trans first! Plus they only covered the transmission for $2000 in previous versions of their warranties...

OUR TOTAL LIABILITY PER COVERED VEHICLE UNDER THIS WARRANTY IS LIMITED TO $11,500.00 (AGGREGATE). EACH COVERED COMPONENT HAS ITS OWN AGGREGATE VALUE WHICH WHEN COMBINED EQUALS THE TOTAL LIABILITY PER VEHICLE. THE ENGINE IS COVERED FOR $7500.00, $2000.00 PER TRANSMISSION, AND $1000.00 PER REAR AXLE. VEHICLES EQUIPPED WITH A TRANSFER CASE RECEIVE $1,000.00 COVERAGE ON THESE COMPONENTS. VEHICLES WITHOUT A TRANSFER CASE FORFEIT ANY CASH REFUNDS OR REPAIR CREDITS. THESE AMOUNTS CANNOT BE COMBINED TOGETHER TO AID IN THE REPAIR OF ANOTHER COVERED COMPONENT. IN THE RARE CASE WHEN THE REPAIR COST EXCEEDS THE ACTUAL CASH VALUE OF THE VEHICLE, WE WILL REFUND THE PURCHASE PRICE OF THE FORD PERFORMANCE PARTS SUPERCHARGER KIT ONCE THE COMPLETE KIT IS RETURNED PREPAID TO US.

I would recommend the 1-7/8 headers. That is a great size, especially when adding forced induction. Let us know if you have any more questions, or if we can help you get set up with some, we are more than happy to help!

We also have our Spring Sale going on right now, make sure to check it out! We have Stainless works headers, and much more on sale!

We typically recommend 1 7/8 until 9-1000whp.. the 2" are fine at a tad lower levels, but an unnecessary addition. You have to lower the motor/trim the studs for most 2" applications.

If you ever end up wanting to go with headers (I saw the comment on the 3/36k warranty), checkout our Lethal ones. They are 1 7/8" and fit perfectly.

Oof…thank you for that!

I have the stage 1 on my Dark Horse for the warranty too. After 3 years I'm going to upgrade to stage 2. As for headers I plan on going with 1 7/8 Kook's with cat's.

that’s great in theory.
I’ve worked in the auto industry for 20 years. Never seen a customer win that argument yet.

if you had the money for the attorneys to win the lawsuit, you wouldn’t be buying a Mustang.

the hard truth is they can and will void whatever warranty they want if the dealer / OEM decides to.

plenty of folks out there tout the Mag Moss act- still waiting to see someone that won that in the courts.

everyone else just holds onto that pie in the sky dream (and it is a nice thought) but ultimately will lose that argument without taking the dealer / OEM to court and lets be honest - they have deeper pockets than the customers (typically)

This post^^^^^^^ makes some good points. I used to be over a company that built capital equipment used on streets, roads, and off-road. Nobody ever pulled the Magnuson-Moss act on us, but make no mistake, if an OEM wants to void a warranty, they will.

My company never had to do it but get very pushy with a larger company and like Stanzi said, you had better have some lawyer funds set aside. Same with a Ford dealer. Some of them are very well healed and some are not good places to fight with. It's never good to fight in business come to think of. Courtrooms are good places to stay out of. I've been through it with other issues and it can get really nasty. We won, BTW partly because we outspent them and partly because they were wrong. Find other ways to solve problems.

Everyone is an authority on M-M but no one has a real clue. People just want to parrot back the misinformation they’ve heard along the way.

In the M-M act the burden of proof is on YOU to prove your aftermarket parts/mods did not not cause the OEM product to fail- that is a VERY long and expensive uphill battle.

It was funny to see that here because the dumb old boomers on the Corvette Forums love to throw M-M out every chance they get without having a clue.

Excellent advice about suing an entity with a million times the plaintiff's financial resources.
