  1. My 1st Mustang-how to quiet it down

    I can find nice OEM Mustang takeoff systems on OfferUp almost weekly in my area. https://offerup.com/
  2. Gen 4 Coyote Tuning, when???

    What a dystopian thread this has become. Reminds me of all the bitching that the Hot Rod performance world was ending because lead was removed from pump gasoline. All the hype and crying about valve seats being destroyed without lead to cushion the valve closing. Yet here we are some 45 years...
  3. My 1st Mustang-how to quiet it down

    Post #40 answered that question. No Helmholtz on those MBRP’s. There’s no hope for that cobbled up mess, scrap it.
  4. My 1st Mustang-how to quiet it down

    Same system. Keep in mind you’ll be going from 3.0” header connections down to 2.25 connections if you get the stock exhaust system.
  5. My 1st Mustang-how to quiet it down

    Nice. If the OP has that style MBRP then the mid Jones muffler is most definitely the place to start his dB reduction quest.
  6. My 1st Mustang-how to quiet it down

    Do you have a mid resonator installed on your MBRP ? Jones, Stainless Bros, Borla or dual bottle style ?
  7. My 1st Mustang-how to quiet it down

    The OP hasn’t mentioned his budget. The Jones mid is a $70.00 part. His neighbors can’t hear the drone but nonetheless muffler style or adding Helmholtz is the drone solution. @gsrblack Does your MBRP have Helmholtz chambers ?
  8. 5w30 engine oil swap now engine making noise

    To much pampering. Start using 0W-40 or 5W-40 euro spec.
  9. My 1st Mustang-how to quiet it down

    It’s an affordable starting point that will lower the dB’s being the car has full length headers.
  10. My 1st Mustang-how to quiet it down

    Before you do anything else install the Jones in place of your H-pipe. https://www.summitracing.com/parts/jex-mf2469?srsltid=AfmBOoqxPKvARC0EE75N0l6aE27PCyLiNv8x_EG6zwGLE5H91EHaxIqu
  11. MT82-D4 Shuddering When Taking Off From 1st gear

    Mine also does it in reverse. No chatter but I will say my shudder is very consistent. Now if I lean into it and drop the clutch in a moderately aggressive manner it shits and gets. Less time for shudder pulses I imagine.
  12. Viscosity decrease after 8 hours track time?

    Redline 5W-50 if you don’t mind the price.
  13. Quick question can a 2024 Stock intake box fit on a Gen 3 Mustang GT?

    I’m mystified as to why the GT350 manifold gets passed over so often. The GT350 has a 89mm plenum opening and can be opened further if removing the TB sealing gland. Fitting a 90-100mm+ TB isn’t an issue and Soler Perf. has made this possible. Tuning on the other hand could probably be handled...
  14. S650 Manifold Twin 80mm TB map based on S550

    I’m wondering if the Gen4 TB motor wiring gauge is uprated for the dual TB’s vs. Gen1/2/3. Just thinking load rating over the long term.
  15. S650 Manifold Twin 80mm TB map based on S550

    I like Wizard and VooDoo threads. Even if I can’t keep up I'm learning something !
  16. S650 Manifold Twin 80mm TB map based on S550

    Isn’t safe to say Derel is running his Gen3 dual TB’s at 1:1 ? Wouldn’t it require separate TB servo motor wiring to control each one independently ?
  17. WTF is Rec90 gas?

    We have that and open road tolling. Both are an improvement but the volume of traffic is just staggering anymore. It’s a mess when the traffic light sequence is disrupted.
  18. WTF is Rec90 gas?

    Here in the armpit of the Chicago area no one moves far enough to achieve the upper limits of CAFE. Millions of humans trapped in a tin can fighting one stop light after another. I totally get using real gasoline and the MPG gain but around this area we’re all stuck bumper to bumper and...
