Integrated Merge Spike


The Integrated Merge Spike

Small details can make a big difference when it comes to performance.

That's why we're proud to introduce the newest feature to our line of exhaust systems: the integrated merge spike. Designed to promote better airflow, all Stainless Works V8 long-tube headers are now manufactured with high-performance, integrated merge-spikes.*

Merge Spike Airflow



Increased Power

Too much air resistance or back-pressure, can make it difficult for the cylinders to expel exhaust, restricting an engine's power. Merge spikes help reduce turbulence, which means less back-pressure; allowing your engine to unleash more power.

Better Scavenging

Inspired by race-system technology and performance dyno testing, the Stainless Works merge spike was developed to direct airflow towards the center of the collector, which helps promote scavenging.

Improved Sound

The other benefits of creating a more directional airflow is that the turbulence within the collector is reduced; improving performance, and generating a purer sound.

Hear the Merge Spike in action on in our video section.

Merge Spike Design

As with all of our products, the Stainless Works merge spike is made from durable, Everlast 304L Stainless Steel.
