Description
Exhaust Manifold 1.1, 1.4 and 1.6 8V Citroën Peugeot
Exhaust Collector
The Exhaust Manifold for 1.1, 1.4 and 1.6 8V Citroën and Peugeot engines is a direct-fit replacement part designed to route exhaust gases from the cylinder head into the exhaust system. Ideal for professional workshops and DIY mechanics, this manifold restores proper exhaust flow, reduces leaks and helps maintain engine performance and fuel efficiency. Commonly searched by part numbers 9661916480 and 0341F9, this collector suits a range of popular small-engine models and is a frequent item in repair and maintenance jobs.

Function And Benefits
The manifold (exhaust collector) collects exhaust gases from the engine cylinders and channels them to the downpipe and the rest of the exhaust system. A correctly sealed and structurally sound manifold prevents exhaust leaks, avoids loss of backpressure that can affect drivability, and reduces the risk of hazardous fumes entering the cabin. Replacing a damaged manifold can restore idle stability, improve acceleration response and eliminate ticking or hissing noises at the engine bay.
Signs Of Failure
- Audible ticking, popping or hissing noise from the engine bay, especially on cold start or acceleration.
- Loss Of Power Or Poor Throttle Response.
- Strong Exhaust Smell In Engine Bay Or Cabin (indicates leak).
- Check Engine Light May Appear If Leak Affects O2 Sensor Readings.
Why The Part Commonly Fails
Failures Are Typically Caused By Corrosion From Moisture And Road Salt, Thermal Fatigue Due To Repeated Heating And Cooling Cycles, And Gasket Deterioration At The Cylinder Head Interface. On Older Vehicles, Cracks Or Warping Can Develop Where The Manifold Mounts To The Head Or At Weld Joints. Poor Torqueing Or Repeated Repairs Can Also Damage Flange Faces And Fasteners.
Replacement And Installation Recommendations
Replacement Is Straightforward For Experienced Technicians But Requires Proper Procedure:
- Allow The Engine To Cool Completely Before Starting Work.
- Disconnect The Battery To Prevent Electrical Shorting While Working Around Sensors And Heating Elements.
- Remove Heat Shields And Any Obstructing Components (Intake Piping, Wiring Harness Clips, O2 Sensor If Necessary).
- Loosen Exhaust Fasteners Gradually In A Cross Pattern To Avoid Distorting The Flange.
- Clean The Cylinder Head Flange Surface Thoroughly And Inspect For Warpage Or Damage. Replace Gaskets And Use New Bolts/Nuts If Old Fasteners Are Corroded.
- Fit The New Manifold Using The Correct Torque Settings From The Manufacturer And Reinstall Heat Shields And Sensors.
- After Installation, Start The Engine And Check For Leaks, Unusual Noises And Proper Sensor Operation.
Recommended To Use Anti-Seize On Stud Threads Where Specified And Replace Exhaust Gaskets During Any Manifold Service.
Practical Notes For Mechanics
Fasteners On These Manifolds Often Seize Due To Heat And Corrosion — Using Penetrating Oil And Heat Can Help Remove Old Nuts. Inspect O2 Sensors And Wiring For Heat Damage; replace If Required. If Flanges Are Severely Corroded Or Warped, A Replacement Manifold Is Preferable To Welding Repairs On Thin Cast/Stamped Steel Parts.
Compatibility
Fits 1.1 8V, 1.4 8V And 1.6 8V Engine Variants In The Following Models: Citroën C2, Citroën C3, Citroën C3 Pluriel, Peugeot 206, Peugeot 206+, Peugeot 207. Always Cross-Check Part Numbers 9661916480 And 0341F9 With The Vehicle’s Existing Part To Confirm Fitment.
Additional Advice
Replacement Frequency Varies By Use And Environment; Manifolds In Cars Operating In Coastal Or High-Salt Areas And Vehicles With Frequent Short Trips Tend To Corrode Faster. Inspect The Manifold During Routine Service Intervals Or When Symptoms Appear.
