Stop the Rattle Before It Starts
The factory flex pipes on the 2020 to 2024 Ford Explorer ST are a known weak point, prone to rattling loose and eventually failing as the vehicle ages. The A910 mid pipes from Thermal R&D replace those factory sections with a durable 2.5 inch T304 stainless steel pipe built to connect directly to Thermal R&D catback exhaust systems, giving Explorer ST owners a reliable, long term fix at the mid pipe connection point.

FAQ
What is the A910?The A910 is a 2.5 inch T304 stainless steel mid pipe set built by Thermal R&D to replace the factory flex pipes on the 2020 to 2024 Ford Explorer ST and connect to a Thermal R&D catback system.
Will this fit my Explorer ST by itself without a catback?These mid pipes are designed to connect to a Thermal R&D catback exhaust system rather than the factory rear muffler, so they are intended to be installed alongside a compatible catback rather than as a standalone replacement.
Do I need any special tools to install it?Standard hand tools and a way to safely lift and support the vehicle are all that is needed since the mid pipes bolt on using OEM hanger and clamp locations.
Will installing the A910 require cutting or welding?No cutting or welding is required, the mid pipes bolt in place using the factory connection points and clamps.
Does this part come with a warranty?Yes, the A910 is backed by a lifetime warranty from Thermal R&D against manufacturing defects.
Can I install these mid pipes myself at home?Most owners with basic exhaust experience and jack stands can complete the install in a home garage without needing a lift.
Will this part cause any check engine lights or codes?Since it is a mid pipe section that does not include catalytic converters, it should not trigger emissions related codes when paired with a compatible catback system.
What is your return policy on the A910?Unused parts in original packaging can be returned within our standard return window, please contact us before shipping anything back so we can provide instructions.
Install Instructions
- Apply penetrating fluid to the factory exhaust hangers and clamps before starting.
- Safely elevate the vehicle on jack stands.
- Disconnect the factory flex pipe section at the clamps and unclip the hanger isolators.
- Remove the factory flex pipe section from the vehicle.

- Connect the compatible Thermal R&D catback system to the rear of the mid pipes.
- Align all sections, then torque clamps to specification.
- Start the engine and inspect every joint for exhaust leaks.
