Straight Aluminum 4in OD x 18in Long

The Straight Aluminum 4in OD x 18in Long tubing by VIBRANT PERFORMANCE is a precision-engineered exhaust and intake component designed for serious automotive builders and performance mechanics. This aluminum tube serves as a critical building block for custom exhaust systems, air intake manifolds, intercooler piping, and turbocharger ducting on both street and competition vehicles. Whether you're fabricating a complete exhaust system for a forced-induction engine or designing custom intake runners, this straight tube offers the dimensional stability and material consistency required for professional-grade installations.

Constructed from lightweight aluminum with a 4-inch outer diameter and 18-inch length, this tubing delivers excellent thermal properties and corrosion resistance—essential qualities for exhaust applications where temperature cycling and moisture exposure are constant threats. The straight configuration eliminates the time and tooling costs associated with mandrel bending, making it ideal for custom fabrication where you need precise, welded joints and custom-bent sections. Aluminum's inherent strength-to-weight ratio means you can reduce system weight without sacrificing structural integrity, a critical factor in performance applications where every pound impacts throttle response, acceleration, and overall drivability.

This tube is ideal for fabricators working on turbocharged, supercharged, or naturally aspirated engines requiring custom piping solutions where off-the-shelf components won't fit. Professional mechanics and kit car builders rely on VIBRANT PERFORMANCE's dimensional accuracy and consistent wall thickness for repeatable, leak-free welds. At 2.36 lbs, the material remains light enough for suspension-critical applications while maintaining the rigidity needed for high-pressure exhaust gas or intercooler coolant flow. Compatible with standard TIG and MIG welding techniques, this straight section integrates seamlessly into modular exhaust and intake systems.
