Maximum Flow. Maximum Torque. Maximum Performance.
The SPDZ1 K-Series K20/K24 Megaphone 4-1 Tri-Y Race Header is built for serious K-swap enthusiasts who demand nothing but peak performance and aggressive sound. Designed to extract every ounce of power from your K-series engine, this header combines a long-tube 4-1 Tri-Y layout with a true megaphone-style collector that delivers explosive throttle response, improved mid-to-top-end power, and that raw race-car growl.
Unlike restrictive factory manifolds or shorty headers, the SPDZ1 unit uses a 3” V-band collector for seamless flow, ease of installation, and superior boost potential for turbo setups. Whether you’re building a weekend warrior or a full track weapon, this header will bring your K-swap to life.
Key Features:
For K-Swap Applications: Fits K20/K24 swapped EG, EK, and DC2 chassis
4-1 Long Tube Tri-Y Design: Optimized for power gains across the RPM range
True 3” Megaphone V-Band Collector: Maximum exhaust velocity and torque, plus easy install/removal
CNC Machined 3/8” Flanges: Durable, leak-free connection that won’t warp under heat
Ported Primary Flanges: For uninterrupted exhaust flow and velocity
High Ground Clearance Design: Offset primaries for lowered builds
Includes Gaskets, Springs, and Hardware: Everything you need to bolt up and go
Crafted from Premium 304 Stainless Steel: TIG-welded for strength and longevity
