3.5In Oval T304 Stainles Steel Straight Tubing

The 3.5In Oval T304 Stainless Steel Straight Tubing (SKU VIB13183) from VIBRANT PERFORMANCE is a precision-engineered exhaust pipe designed for builders and mechanics seeking seamless flow characteristics and corrosion resistance. Built for custom exhaust fabrication, this oval-profile tubing accommodates modern engine packages where traditional round piping cannot optimize space or aerodynamic flow. Whether you're constructing a catback system, header collector transition, or mid-pipe assembly, this straight section serves as a critical foundation for both performance and longevity in high-temperature exhaust environments.

Manufactured from T304 stainless steel, this tubing delivers superior corrosion resistance compared to mild steel alternatives, making it ideal for vehicles exposed to salt, moisture, and thermal cycling. The oval cross-section—measuring 4.063 inches wide by 2.438 inches tall—maximizes internal volume while minimizing frontal area, reducing exhaust backpressure and improving scavenging efficiency. At 16-gauge wall thickness, the tubing balances durability with weight, providing structural integrity without adding unnecessary mass. The full 60-inch length allows flexibility for routing around chassis obstacles and engine bays of varying configurations, while the 13-pound weight keeps overall system mass minimal—critical for performance-oriented builds where every pound matters.

This oval stainless steel straight tubing is ideal for builders fabricating custom exhaust systems on turbocharged, supercharged, and naturally aspirated platforms. Installation requires basic welding skills and compatible flanges or adapters at each end; most builders integrate it between turbo outlets, catalytic converters, or muffler inlets. The natural mill finish accepts ceramic or metallic coatings for enhanced heat management, or remains bare for authentic stainless aesthetics. Verify your vehicle's space constraints and flow requirements—oval geometry excels in tight engine bays and aggressive underbody layouts where round tubing creates fitment conflicts.
