BMW E30 Long Tube Exhaust Headers
Give the E30 straight-six exhaust path a freer-flowing long-tube layout while adding a deeper, more purposeful exhaust tone. These FLASHARK stainless steel headers are listed for selected 1988–1993 BMW E30 320i, 323i, 325i and 325ix applications and replace the factory-style exhaust manifold at the engine.

Key Features
- Long-tube layout: Replaces the compact factory-style exhaust manifold with individual runners leading toward the collector.
- Stainless steel construction: Provides a corrosion-resistant alternative to a heavy cast-iron manifold.
- Mirror-polished finish: Gives the header assembly a clean, finished appearance.
- Naturally aspirated exhaust character: Designed to support smoother exhaust movement and a deeper tone through the E30 inline-six exhaust system.
- Platform-specific positioning: Intended for the listed E30 applications rather than later BMW M54, M30 or four-cylinder platforms.
Built for Better Flow and Sound
A factory exhaust manifold uses a compact layout that prioritizes packaging, durability and production requirements. A long-tube header gives each cylinder a longer exhaust path before the pipes merge, changing exhaust pulse behavior and reducing some of the restriction associated with the factory-style manifold.
Throttle response, upper-rpm pull and sound can vary with engine condition, the remaining exhaust system and installation quality. The rear exhaust, catalytic-converter layout, resonators and muffler have a major influence on volume, rasp and cruising drone.
Factory-Style Manifold vs. Long-Tube Header
| Area | Factory-Style Manifold | FLASHARK Long-Tube Header |
|---|---|---|
| Construction | Compact cast-style layout | Stainless steel tubular layout |
| Runner Layout | Short, compact exhaust paths | Longer individual exhaust paths before merging |
| Sound | Closer to the factory exhaust character | Deeper, more pronounced inline-six tone depending on the full exhaust |
| Installation Planning | Factory connection layout | Requires clearance, sealing and downstream-exhaust checks |
What Is Included
- FLASHARK long-tube exhaust header assembly for SKU FLES08348
Review the selected product configuration before installation. Replacement sealing parts and service hardware should be chosen for the vehicle and exhaust layout being serviced.
Installation Notes
Technician’s note: Long-tube header installation should be planned as an exhaust-system job, not only a manifold swap.
- Inspect the cylinder-head sealing surfaces and mounting threads before assembly.
- Check clearance around the steering system, transmission area, drivetrain components and body.
- Compare the header outlet with the existing mid-pipe or cat-back connection before final tightening.
- Use suitable sealing components and tighten fasteners evenly to reduce the chance of an exhaust leak.
- Recheck fasteners and inspect for leaks after the first complete heat cycles.
- Keep wiring, hoses and heat-sensitive components away from the exhaust runners.
Who These E30 Headers Are For
- Owners of a listed E30 inline-six application replacing or upgrading the factory-style exhaust manifold.
- Drivers looking for a more pronounced exhaust tone from a naturally aspirated BMW straight-six.
- Performance-oriented street, project or track builds where installation and exhaust-system compatibility can be assessed.
- Owners prepared to check the complete exhaust path rather than assuming every existing mid-pipe or cat-back will connect without adjustment.
Who Should Choose a Different Exhaust Part
- E30 318is owners with the four-cylinder M42 engine.
- Owners shopping for a complete cat-back or full exhaust system rather than headers.
- Drivers who require factory exhaust sound and factory-style packaging.
- Vehicles whose engine, drivetrain or steering configuration does not match the listed applications.
- Owners who require an emissions-approved replacement without first checking local requirements.
Emissions and Street-Use Notice
Exhaust modifications can affect emissions equipment, inspection eligibility and road-use compliance. Check the vehicle’s catalytic-converter layout, oxygen-sensor arrangement and applicable local regulations before installation. Do not assume that an aftermarket header is emissions-approved or street legal in every jurisdiction.
