About Thermal R&D
Thermal R&D engineers every exhaust system around real world frequency testing rather than a generic muffler swap. For the Explorer ST platform, Thermal identified the factory flex pipe and mid pipe as a recurring failure point and built the A/B/C 910-C direct replacement into the downpipe back design so owners solve a durability issue while upgrading sound and flow at the same time.

FAQ
What is the A/B/C 910-C?The A/B/C 910-C is Thermal R&D's 2.5 inch downpipe back exhaust system for the 2020-2026 Ford Explorer ST, including new mid pipes and finished with black coated tips.
Does this system replace the factory mid pipes?Yes. Unlike a catback only system, this downpipe back kit replaces the factory mid pipes and flex pipes, which is a common failure point on the Explorer ST.
Will this fit the base, XLT, Limited, or Platinum Explorer?No. The A/B/C 910-C is designed specifically around the 3.0L EcoBoost V6 used only in the Explorer ST and does not fit other Explorer trims.
Is professional installation required?Most installers complete this exhaust in an afternoon using factory hangers and hand tools, though a lift makes the mid pipe section easier to access.
Does replacing the mid pipes affect emissions?No. The system connects behind the OEM catalytic converters, so factory emissions equipment and readiness monitors are not affected.
Will I hear more drone on the highway with the larger downpipe back design?Thermal R&D's True Helmholtz Technology is tuned specifically to prevent that, so highway cruising stays quiet despite the increased flow.
What is covered under the warranty?Thermal R&D backs this system with a lifetime warranty against manufacturing defects in materials and welds.
Can I choose polished tips instead of black coated?Yes, Thermal R&D offers the A/B/C 910-C platform with polished tips as a separate configuration if you prefer that finish.
Install Instructions
- Raise the vehicle and support it securely, then let the factory exhaust cool completely.
- Remove the factory exhaust starting at the catalytic converter outlets and working back.
- Detach the factory mid pipes and flex pipes, then remove the assembly from the vehicle.
- Install the new front pipes to the OEM catalytic converter outlets using the supplied clamps.
- Secure the new mid pipe and center muffler section to the front pipes.
- Attach the rear muffler section with black coated tips and seat it on the factory hangers.
- Align the tips evenly at the rear valance, then torque all clamps to spec and check for leaks.
