Why Choose an SLS 3D Printed 4 Into 1 Exhaust Collector?
A well-designed collector is one of the most important components of any high-performance exhaust system. The efficiency of the merge directly influences scavenging, flow characteristics and overall engine performance. By utilising advanced SLS 3D Printing, our collectors achieve internal geometries that are simply not possible using conventional cut, formed and welded construction.
Unlike traditional fabricated collectors, each Krolltek 4 into 1 merge collector is produced as a single precision-engineered component from 316L stainless steel. This allows smooth internal transitions, consistent wall thickness where required, and exceptional dimensional accuracy. The result is improved exhaust flow, increased strength and a repeatable product that fits exactly as intended.
Developed using our experience in motorsport and high-performance fabrication, these collectors are ideal for naturally aspirated engines, turbocharger manifolds and custom exhaust builds. Whether you're a competition car, race engine or bespoke road vehicle, our SLS collectors provide the quality and precision expected from professional motorsport components.
Designed for Professional Fabrication
Every collector is manufactured using premium 316L stainless steel, offering excellent corrosion resistance, durability and weldability. The precision of the SLS manufacturing process ensures every part is identical to the last, making fabrication quicker, more consistent and easier for professional fabricators and enthusiasts alike.
Our 4 into 1 exhaust collectors are suitable for a wide range of custom applications and are available in multiple inlet and outlet sizes to suit your project.
If you require a bespoke collector or a fully custom exhaust manifold, Krolltek Fabrication also offers a complete design and manufacturing service using advanced CAD modelling and additive manufacturing techniques.
