2015-2020 Ford F-150 Cat-Back Exhaust for Deeper Sound and Better Flow
A truck exhaust upgrade should make the F-150 feel more alive without turning every cold start, highway cruise, or trailer run into a headache. This system is built for owners who want a deeper tone, better rear-end style, and a cleaner exhaust path after the catalytic converter.
This 3-inch cat-back exhaust fits 2015-2020 Ford F-150 trucks with the 2.7L EcoBoost, 3.5L EcoBoost, or 5.0L V8 engine. It is available in polished side exit, polished dual split exit, and black dual split exit styles, so you can match the sound and look to how your truck is actually used.

Built for Better Flow and a Stronger Exhaust Note
The factory F-150 exhaust puts quiet operation first. That is fine until you want to hear more of the engine you paid for. Moving to a 3-inch cat-back changes the exhaust path behind the catalytic converter, giving the rear section a freer-flowing route and a noticeably stronger tone under throttle.
- 3-inch main piping supports smoother exhaust flow through the rear section.
- T-304 stainless steel adds corrosion resistance for year-round truck use.
- Mandrel-bent tubing helps maintain a more consistent internal diameter through bends.
- Polished and black exit options let you match the exhaust to the rest of the truck.
- The factory catalytic converter remains in place.
- No ECU tune is required for a normal cat-back installation.
5.0L V8 vs 2.7L and 3.5L EcoBoost Sound
Engine choice changes the result more than the tip finish does. A 2015-2020 F-150 5.0L V8 has the deeper, slower exhaust pulse most owners associate with a traditional V8 truck. The 2.7L and 3.5L EcoBoost engines produce a tighter, sharper note. They get deeper than stock, but they do not suddenly turn into a 5.0L.
| Setup | At Idle | Under Throttle | Daily-Driving Character |
|---|---|---|---|
| Stock Exhaust | Quiet and subdued | Mild | Factory-focused comfort |
| 5.0L V8 + Cat-Back | Fuller V8 note | Deeper and more aggressive | Most noticeable sound change |
| 2.7L / 3.5L EcoBoost + Cat-Back | Deeper than stock | Tighter, stronger turbo-V6 tone | More presence without pretending to be a V8 |
Side Exit or Dual Split Exit?
| Style | Best Match | Character |
|---|---|---|
| Polished Side Exit | Clean, traditional truck layout | Visible polished finish with sound directed toward the side of the truck |
| Polished Dual Split Exit | Owners wanting a more noticeable rear-end change | Classic bright dual-exit appearance |
| Black Dual Split Exit | Dark wheels, black trim, or stealth-style builds | Aggressive dual-exit layout with a darker finish |
What Changes Compared With the Stock F-150 Exhaust?
| Area | Stock Setup | 3-Inch Cat-Back |
|---|---|---|
| Sound | Quiet and restrained | Deeper and more noticeable under throttle |
| Rear-Section Flow | Designed around factory noise and packaging targets | 3-inch free-flow path through the cat-back section |
| Appearance | Factory tailpipe styling | Polished or black side / dual split exit options |
| Catalytic Converter | Factory | Remains in place |
| ECU Tune | Factory calibration | No tune required for normal installation |
Performance Expectations
A cat-back should not be treated like a major engine modification. Its job is farther downstream: reduce restriction through the rear exhaust section, change the sound, and support cleaner exhaust movement after the catalytic converter.
Depending on engine condition, the rest of the exhaust setup, tune status, fuel, testing method, and installation quality, this system supports an estimated gain of approximately 8-16 HP and 6-13 lb-ft of torque. The exact result will vary from truck to truck.
Technician's Note: Buy a cat-back because you want a stronger exhaust note, stainless rear-section piping, and a different exit style. Treat any horsepower increase as a supporting benefit rather than the only reason to install one.
Where This Cat-Back Fits in the F-150 Exhaust System
This system works in the exhaust path behind the factory catalytic converter. It does not replace the exhaust manifolds, turbo downpipes, catalytic converter assembly, or front emissions hardware.
That distinction matters on both the 5.0L and EcoBoost trucks. Owners looking at a 2017 or 2020 Ford F-150 exhaust system diagram can use the same basic reference point: the cat-back is the rear section of the exhaust rather than a complete engine-to-tailpipe system.
Who Is This Cat-Back Best For?
- 2015-2020 F-150 owners within the listed engine, drivetrain, and body fitment.
- 5.0L V8 owners who want a fuller, more traditional truck exhaust note.
- 2.7L or 3.5L EcoBoost owners who want more exhaust presence without expecting V8 sound.
- Drivers who prefer a complete cat-back upgrade rather than changing only the muffler.
- Owners who want a polished or black side / dual split exit appearance.
- Drivers who want a rear-section exhaust upgrade without requiring an ECU tune.
When a Different Exhaust Setup Makes More Sense
- Your F-150 falls outside the listed 2015-2020 fitment range.
- You only need to replace a damaged factory muffler and do not want a full cat-back upgrade.
- Your goal is to replace headers, turbo downpipes, catalytic converters, or other front exhaust components.
- Your truck already has custom-cut or welded exhaust piping that changes the factory connection points.
- You are looking for an extremely quiet, factory-level exhaust note.
Installation Notes
This system uses a bolt-on style installation. A skilled DIY owner with proper lifting equipment and hand tools may be able to complete the work at home, but professional installation is recommended.
Rusty factory clamps, seized hardware, previous exhaust repairs, or non-stock piping can add work. Support the exhaust before loosening the old system, leave the new connections slightly loose during initial alignment, center the tips, and tighten the system only after hanger and body clearance look correct.
