Header Set

Description

Header Set

1/25 Scale Asphalt Modified

A precision‑printed set of competition‑style headers designed for builders who want accurate exhaust detail, crisp tube geometry, and a paint‑ready finish straight out of the package. These headers replicate the tight‑fit, high‑flow designs used on full‑scale Asphalt Modified engines, with realistic tube routing and collector shape.

Each header is 3D printed on Elegoo Mars 3 Pro–series resin printers using high‑resolution settings to capture the tube bends, collector transitions, and mounting flange detail. Supports are generated in CHITUBOX Software to ensure stability during printing while keeping cleanup minimal.

Every part is cleaned with degreaser and 91% isopropyl alcohol, fully cured, and delivered ready for primer and paint.

Detailed Description (Based on the Photo)

The Header Set features realistic exhaust‑system geometry and fabrication detail, including:

• Four‑Tube Primary Layout Each header shows four evenly spaced primary tubes with clean bends and proper scale thickness. The tubes follow the tight, forward‑swept routing typical of Modified chassis where space is limited.
• Smooth Tube Bends The photo shows crisp, uniform curves with no flattening or distortion — ideal for metallic paints, heat staining, or weathering effects.
• Defined Collector Section The collector transitions cleanly from the four primaries into a single outlet, replicating the look of welded steel racing collectors.
• Correct Mounting Flange Geometry The head‑mount flange includes clean edges and realistic thickness, visually aligning with 1/25 cylinder heads and engine blocks.
• Left and Right Header Pair The set includes both sides, each mirrored correctly to match real small‑block Modified header configurations.
• Clean Resin Finish Smooth surfaces across all tubes and collectors make these headers ideal for detailed paint work — from raw steel to ceramic‑coated finishes.
• Realistic Fabrication Style The overall shape replicates the hand‑built, TIG‑welded headers used in full‑scale competition engines.

This header set integrates seamlessly with Hurd Hobbies engine blocks, cylinder heads, manifolds, ignition components, and full engine builds.

Key Features

• Ready to Paint: Fully cleaned, cured, and prepped for primer.
• Professional Resin Workflow: Degreased and rinsed with 91% IPA for a residue‑free finish.
• High‑Detail Printing: Produced on Elegoo Mars 3 Pro (and Mars‑series equivalents) for crisp edges and smooth transitions.
• Optimized Support Strategy: CHITUBOX‑generated supports minimize sanding and preserve fine structural details.
• True‑to‑Scale Geometry: Designed specifically for 1/25 Asphalt Modified builds — SMART Tour, Whelen Modified, and similar chassis styles.

What You Receive

A clean, crisp, paint‑ready Header Set that adds authentic, competition‑grade exhaust detail to any 1/25 Asphalt Modified engine build.
