  1. Dark Horse Stage 1 Warrantied

    My dyno man has a heavily modded S550 with long tubes and huge cats. He runs a Stage 3 Whipple and drag races with no problems with cats melting.
  2. So Long and Thanks for All the Fish...

    Yes, hang out and chat! Discussion is the heart of this site. You'll get through this and may well be in a Dark Horse SC before long!
  3. Dark Horse Stage 1 Warrantied

    My dyno man said stage 1 should be fine unless I do back to back full throttle blasts repeatedly. Stage 2 will definitely want high flow cats, which I have ready to install along with my LT headers.
  4. Dark Horse Stage 1 Warrantied

    That's amazing, I'm doing the same with my '25 DH. I am putting a double H pipe on at the same time. I had long talk with my dyno and build shop owner and he pulled up the Whipple warranty and we can't change anything inside the engine or exhaust cats forward or the warranty will be void. When...
  5. Flat tire at under 400 miles

    Actually, my friend's house is only about 4 miles from our local Costco. I used his shop compressor and put in 40 psi, jumped in and made it to Costco with about 21 psi remaining. They weren't that busy and fixed it right away. I've had them fix punctures several times and have never had a...
  6. Trafeo tires - replaced at what mileage?

    I've had nothing but fantastic results running the Michelin PS4S tires on cars I have. I was a bit disappointed when I found that Ford put the Pirellis on the DH. When my Pirellis are cooked I'll definitely go back to Michelins.
  7. Flat tire at under 400 miles

    Well, I had a real nutty afternoon. My 2025 DH had a flat on the left rear. I went to help a friend with his car and when I was ready to leave, my driver's side rear tire was flat! I'm at Costco getting it fixed. What kick in the teeth. It has just under 400 miles on those Pirellis. Fortunately...
  8. Anyone that bought a 2025+ remember to file your taxes

    Once again, I'm being punished for saving up and buying my DH outright and not financing it...
  9. Anyone that bought a 2025+ remember to file your taxes

    I paid for my Dark Horse when I picked it up. My aunt passed away and left me enough to pay for a '25 DH Premium. I do have several charitable donations it sounds like I can deduct now!
  10. Dark Horse vs Dark Horse Premium

    I have a '25 DH Premium with standard seats. It was my choice not to get Recaros, I simply don't fit in them well.
  11. Dark Horse Coffee

    It's especially good with Whippled cream on top! 😁
  12. Setting of heated seats

    I'll check it out. I only have about 340 miles on the car with it being winter. It was 61° here yesterday and I had it out to get a Whipple and cat back quote.
  13. Short wheelbase Mustang

    That appears to be a track only car. Frankly, I think it's extremely overstated. Especially the boy racer giant wing.
  14. Setting of heated seats

    Originally set my seats to 3 on heat. Now every time I remote start the seats are on 3. My old Escape always started with the seat heaters off. It must be in the presets now.
  15. Is it me or is this car tail happy when making fast turns

    The Torsen differential is particularly good at bringing the rear around. I gave my new DH a bit too much throttle turning left off my street onto another. I got about 30° out and backed off. Fortunately, the car straightened back up and no damage was done. I had a old Fox body years ago that I...
  16. DH connecting rods

    Not to be a spelling prude, they're "sintered" steel and have "cracked" caps. They fit together perfectly and are remarkably strong. The forgings are perfect for high RPM applications involving endurance. The Dark Horse is billed as a track focused Mustang, so Ford put in the good stuff for...
  17. SAVE 10% SITEWIDE AT LETHAL PERFORMANCE WITH CODE: SWEET

    I bought a Stop-the-Hop kit with this and my points! Great deal!
  18. Auto Start/Stop killed by EPA rules deregulation

    My son bought and installed a simple little kit on his Subaru Forester that eliminated the AS/S auto on. It took about 15 minutes to do. Now when he hits the button it enables the feature instead of turning it off. I love it. I should have been off by default. It simply adds wear and tear on the...
  19. RECALL on COWL LEAKS

    My '25 DH was built in August of 25. What dates does the recall cover. In other words, when did the correction hit production. I haven't received a recall notice.
  20. LTH + Borla S-Type + H-pipe or keep the X-pipe?

    I've seen dyno runs that show S550s make better power with an X pipe. But we're only talking about 2-3 HP at the wheels. Oddly, it seems it's reversed on S650s, again, but only a a few HP. H pipes do seem to create that classic rumble where X pipes seem to make more of a raspy sound. I have...
