  1. SPE says they have tuned a 2024 mustang

    We're hoping they will release a full turn key kit with whatever is needed to install and drive. However I don't have all of the details on it yet. Once I do I'll make sure to share it with you guys. Sorry if I misunderstood what you were asking. I read it as why aren't they telling everyone how...
  2. SPE says they have tuned a 2024 mustang

    The point is that they took the time and I'm sure spent some coin to figure something out that's working for them. Why share it with the public so other competitors of theirs can just copy what they're doing and use it to their benefit?
  3. SPE says they have tuned a 2024 mustang

    From my understanding they aren't using a Whipple or Roush file. Nor are they using a standalone system. We work closely with SPE however I haven't really pressed them for details as it's something they may want to keep under wraps at this time.

  6. Ecoboost Exhaust

    There's a couple great options you could go with. Personally, I would recommend the Magnaflow performance cat-back. Comes with dual black tips and it is the competition series. Check it out here...
  7. Long Tube Header Question

    I would recommend the 1-7/8 headers. One of the best sizes, and very popular on the coyote platform. If you are wanting an offroad header system, check this one out...
  8. How is the A10 holding up with the Whipple?

    We raced our DH several times with the Whipple before going to the Stg 3 upgrade from RSA. Never had a single issue with it but we knew we were going to be turning the power up over what we know the stock steel and frictions would be able to support. So after running my [email protected] I had RSA...

  15. Best H pipe?

    Both will sound about the same and have excellent fitment. You will have no problems with either.
  16. Steeda H-Pipe question (Those who have an H pipe or want an H pipe)

    My bad. I was thinking of our 2022 giveaway car when I said touring. The dark horse ran the normal switch path at first before we swapped to the touring.
  17. Steeda H-Pipe question (Those who have an H pipe or want an H pipe)

    Our DH with the stock manifolds, đŸ±'s removed and the AWE switchpath touring system sounded amazing. Nice deep tone to it, zero rasp and zero drone. Great sounding system which you can control with the active exhaust modes. We then put the AWE track edition setup on there which removed the...
  18. Best H pipe?

    Both are great options. If you ever planned to change out to another axleback, looking at the Corsa HH is a good idea, too (or heck, even with stock active). The Steeda one is one of the most common, though, as the quality and price and top notch. A resonator delete would enhance such sound...
