2003-2004 Mercury Marauder headers with high flow catalytic converters. 1 5/8" primary tubes with 3" OD collectors-headers only. Long tube design makes great power and mid range torque. 3/8" SS CNC laser cut flanges are port matched to the cylinder head for optimal flow and maximum performance.

Integrated Merge Spike
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.*
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.
