B925-C926-C 2015-2020 F-150 EcoBoost Dual Exit Catback Exhaust

Dual Exit Sound And Flow For Every EcoBoost F-150 Configuration

This 3 inch dual exit catback exhaust system is built for the 2015 to 2020 Ford F-150 with the 2.7L or 3.5L EcoBoost V6. Constructed from mandrel bent T304 stainless steel, the system replaces the factory single or dual outlet catback section with true dual exit piping that increases flow and gives the EcoBoost a deeper, more resonant tone under boost. Thermal R&D tunes the muffler with its True Helmholtz Technology to keep highway drone under control while preserving an aggressive note under acceleration. The system mounts to the factory catalytic converters and OEM hanger locations, so there is no cutting or welding required, and it is available across every F-150 cab and bed configuration with polished or black ceramic coated tip finishes.

About Thermal R&D

Thermal R&D designs and builds its exhaust systems in Lancaster, California, focusing on flow gains and a controlled exhaust note rather than raw volume. The company's True Helmholtz Technology muffler tuning is used across its catback and frontpipe back lineups to reduce cabin drone at cruising speed while preserving an aggressive tone under acceleration. Every Thermal R&D exhaust system, including this F-150 EcoBoost dual exit catback, carries a lifetime manufacturer warranty and is built from mandrel bent T304 stainless steel for long term corrosion resistance.

Install Instructions

1. Allow the exhaust to cool fully, then raise the F-150 on a lift or jack stands with adequate working clearance.
2. Remove the factory catback exhaust starting at the catalytic converter connection, releasing the factory hanger isolators as you move toward the rear.
3. Test fit the new catback at the catalytic converter connection point, leaving all clamps loose for adjustment.
4. Route the remaining sections through the factory hanger locations, centering the dual exit tips within the rear bumper opening.
5. Adjust the tip alignment and overall system position before tightening any connections fully.
6. Tighten all clamps to the specified torque, start the vehicle, and check every joint for leaks before returning it to service.
