2005–2010 Scion tC 2.4L Long-Tube Exhaust Header
Give your first-generation tC a freer-flowing exhaust path and a more aggressive tone without replacing the entire exhaust system. This Flashark long-tube exhaust header is designed for listed 2005–2010 Scion tC models equipped with the 2.4L inline-four engine and ANT10 chassis.
The header replaces the restrictive factory exhaust-manifold section. Depending on the selected configuration, it can be ordered as the header alone or with the listed catalytic-converter assembly. This is not a complete cat-back exhaust system.

Key Features
- Freer exhaust movement: The long-tube layout provides a smoother route for exhaust gases than the compact factory manifold section.
- Upper-rpm pull: Reduced restriction can support stronger breathing as engine speed rises.
- More aggressive sound: Expect a deeper, more noticeable exhaust note, with the final tone determined by the mid-pipe, catalytic converter, resonator and muffler.
- Estimated performance: Supports an estimated 10–15 HP and 5–10 ft-lbs of torque depending on the complete exhaust setup, tune, engine condition and installation quality.
- Stainless-steel construction: The polished tubing and welded joints are intended for exhaust heat and regular vehicle use.
- Two configurations: Choose the header alone or the header with the listed catalytic-converter assembly.
Better Flow and a More Noticeable Exhaust Tone
A long-tube header changes the exhaust path ahead of the mid-pipe and cat-back. The smoother tubing layout can reduce restriction, sharpen throttle response and improve pull through the upper rpm range.
Sound depends on the rest of the exhaust. A factory-style muffler can keep the result more controlled, while a free-flowing mid-pipe or small muffler can make the exhaust louder and more raspy under acceleration. This header should not be treated as a guaranteed sound level or tone.
Scion tC Header vs. Factory Exhaust Manifold
| Area | Factory Manifold | Long-Tube Header |
|---|---|---|
| Exhaust path | Compact factory layout | Longer, freer-flowing tubing layout |
| Sound | Quieter factory character | Deeper and more aggressive, depending on the remaining exhaust |
| Power delivery | Factory-calibrated response | Can support sharper response and improved upper-rpm pull |
| Installation | Factory configuration | Requires flange, gasket, sensor and downstream-exhaust inspection |
Installation Notes
- Professional installation is recommended.
- Allow the exhaust to cool completely before removing the factory components.
- Support the vehicle with properly rated equipment before working underneath it.
- Inspect the lower flange, spring bolts, threads and sealing surfaces before assembly.
- Do not force an oxygen sensor into damaged or mismatched threads.
- Check oxygen-sensor wiring clearance throughout the full exhaust path.
- Start all fasteners by hand before final tightening.
- After the first heat cycle, inspect the joints for leaks, contact points and loose hardware.
- An aftermarket mid-pipe, S-pipe or cat-back can change alignment and may require professional adjustment.
Technician’s note: A ticking sound, soot around a flange or a sudden change in exhaust tone can indicate a leak. Stop and inspect the gasket surfaces, flange alignment and fastener tension before continued driving.
Who This Header Is For
- Owners of a listed 2005–2010 Scion tC 2.4L ANT10 who want a freer-flowing engine-side exhaust section.
- Drivers who want a deeper, more aggressive exhaust tone.
- Enthusiasts who accept that exhaust sound, installation and power changes depend on the complete vehicle setup.
- Owners prepared to inspect flange compatibility, oxygen-sensor routing and local emissions requirements.
Who Should Choose a Different Exhaust Part
- Owners of a 2011–2016 second-generation Scion tC.
- Drivers looking for a complete cat-back exhaust system rather than a header.
- Buyers who require a guaranteed factory-level sound, guaranteed no-CEL operation or a no-adjustment installation.
- Vehicles that must retain a specific certified factory emissions configuration.
- Owners who cannot accept possible increases in exhaust volume, rasp or installation complexity.
Emissions and Street-Use Notice
Changing the header or catalytic-converter arrangement can affect emissions compliance, readiness monitors and check-engine-light behavior. Requirements vary by location and vehicle configuration. Check local regulations and the selected configuration before use on public roads.

2005–2010 Scion tC 2.4L Header FAQs
Q1: Will this header fit every Scion tC?
A1: It is intended for listed 2005–2010 first-generation Scion tC models with the 2.4L engine and ANT10 chassis. It is not intended for the redesigned 2011–2016 platform.
Q2: Is this a complete 2007 Scion tC exhaust system?
A2: No. It is the engine-side exhaust header, not a complete cat-back system. The mid-pipe, resonator, muffler and exhaust tips are separate parts of the exhaust path.
Q3: What is the difference between a header and an exhaust manifold?
A3: Both terms can describe the component that collects exhaust gases at the engine. This product uses a long-tube header layout intended to provide a smoother exhaust path than the compact factory manifold section.
Q4: How much horsepower can this Scion tC header add?
A4: Estimated output is 10–15 HP and 5–10 ft-lbs of torque, depending on engine condition, the remaining exhaust system, tuning and installation quality. Results are not identical on every vehicle.
Q5: Will it make my Scion tC louder?
A5: Expect a deeper and more aggressive tone. Overall volume and rasp depend heavily on the catalytic converter, mid-pipe, resonator and muffler used with the header.
Q6: Can this header create rasp or drone?
A6: Rasp can become more noticeable with a free-flowing mid-pipe or small muffler. Cabin drone is influenced more by the complete exhaust configuration and cruising rpm than by the header alone.
Q7: Is tuning required after installation?
A7: Tuning needs depend on the complete intake, exhaust and engine configuration. Do not assume tuning will correct a mechanical leak, damaged sensor or emissions-related fault.
Q8: Can the header cause a check-engine light?
A8: A check-engine light is possible when the catalytic-converter arrangement, oxygen-sensor readings or exhaust sealing changes. Read the stored diagnostic code before replacing parts or changing the calibration.
Q9: Will it pass an emissions inspection?
A9: Inspection rules vary by location and by the selected catalytic-converter configuration. Do not assume an aftermarket header is street legal or emissions compliant without checking the rules that apply to the vehicle.
Q10: Does the header bolt directly to every stock or aftermarket exhaust?
A10: Flange condition, gasket thickness, previous exhaust work and aftermarket mid-pipes can affect alignment. Inspect the lower connection before installation and use a qualified exhaust shop when adjustment is required.
Q11: Are all gaskets and fasteners included?
A11: Package contents differ between the header-only and header-plus-catalytic-converter configurations. Check the selected SKU and inspect the supplied components before removing the factory exhaust.
Q12: Can I install the header myself?
A12: Installation requires safe vehicle support, access to exhaust fasteners and careful handling of oxygen sensors. Professional installation is recommended when flange alignment, seized hardware or sensor threads are a concern.
