Description:

Unlock more power and throttle response from your Swift's G13B engine with these direct bolt-on Wildcat Tri-Y extractors. The Tri-Y design improves exhaust scavenging across a broader RPM range compared to standard 4-into-1 headers, giving you stronger mid-range pull without sacrificing top-end performance — and they bolt straight on with no modification required.

Fitment

Specifications

Why Tri-Y Over Standard 4-into-1?

• Tri-Y design pairs cylinders that fire consecutively, improving exhaust scavenging across a wider RPM range
• Stronger mid-range torque and throttle response compared to a standard 4-into-1 header
• Direct bolt-on fitment — no cutting, welding or modification required
• 2-year warranty backed by tax invoice

Frequently Asked Questions

Is this a direct bolt-on fitment?
Yes — these extractors are designed to bolt directly onto the SF413 Swift G13B engine with no cutting or modification required.

Will I need to retune after fitting extractors?
A tune is not strictly required but is recommended to get the most out of the upgrade. At minimum, a tune will ensure the air/fuel ratio is optimised for the new exhaust flow.

Do I need to replace my oxygen sensor or catalytic converter?
These extractors replace the factory exhaust manifold. Depending on your setup you may need an O2 sensor extension lead. If your cat converter connects downstream, it can remain in place.

What does Tri-Y mean?
Tri-Y refers to the pipe configuration — cylinders 1 & 4 and cylinders 2 & 3 are paired before merging into a single outlet. This pairing matches firing order intervals to improve exhaust gas scavenging, which boosts mid-range torque compared to a standard 4-into-1 design.
