Component Specification & Details
1. Genuine Tri-Y Manifolds (Headers)
These are authentic Mercedes-Benz cast-iron “Tri-Y” headers, recently refinished in a high-temp Silver Ceramic Coating. The Tri-Y design (two cylinders merging into one, twice per side) optimizes exhaust gas scavenging, significantly reducing backpressure compared to US-spec manifolds.
| Side | Part Number | Position |
| Right (Passenger) | 117 142 45 02 | Front Section |
| Right (Passenger) | 117 142 46 02 | Rear Section |
| Left (Driver) | 117 142 48 02 | Front Section |
| Left (Driver) | 117 142 51 02 | Rear Section |
2. Rear Section: AMG Sebring Muffler
The system culminates in a legendary Sebring-manufactured AMG Muffler.
-
Design: Twin polished stainless-steel tips with the engraved pre-merger AMG script.
-
Sound Profile: Provides a deep, authoritative V8 rumble at idle that transforms into a crisp, metallic “bark” under heavy acceleration.
-
Condition: Excellent structural condition with original AMG stampings present.
Why This Lot is Rare
-
The “Full Kit”: This is not just the headers; it includes the downpipes, the X-pipe (which replaces the restrictive lateral resonators), and the rear muffler.
-
Ceramic Heat Management: The ceramic coating provides a durable, corrosion-resistant finish that reduces engine bay temperatures—critical for preserving the 40-year-old plastics and wires in a W126.
-
High-Output ECE Spec: Originally removed from a Japanese-market 560SEL (Japanese cars often featured the high-compression European engine), this system is the key to unlocking the full 300hp potential of the M117.
Installation Notes
Wheelbase Compatibility: This system was removed from an SEL (V126) Sedan. While the headers and downpipes are identical for the SEC (C126) Coupe, the mid-section piping on the SEL is slightly longer. SEC owners will need to shorten the mid-pipes to accommodate the 10cm shorter wheelbase.
Hardware Included: The seller (M113Kaiser) has included new copper mounting nuts and flange seals to ensure a leak-free installation.
