Our LS1 Billet Exhaust Flanges feature a raised 25mm butt weld design, which eliminates warpage during welding, unlike traditional flat flanges that can warp due to shrinkage from fillet welds. This ensures a perfect fit and superior durability.

The built-in EGT sensor ports provide easy integration of exhaust gas temperature sensors, allowing for precise monitoring and tuning of your engine's performance, enhancing both efficiency and power.

We use 304 stainless steel for its excellent corrosion resistance, high strength, and aesthetic appeal. Compared to 316 stainless steel, 304 offers better thermal conductivity, which is crucial for high-performance exhaust systems. This improved thermal conductivity helps dissipate heat more efficiently, reducing the risk of overheating and maintaining optimal performance under extreme conditions.

Absolutely. Our flanges are designed to maintain structural integrity and provide a perfect fit, reducing the risk of leaks and maximising exhaust flow, which contributes to improved engine performance and reliability.

On average, it takes around 12 hours to fabricate collectors, which can cost nearly the same as purchasing billet collectors. Our billet collectors not only speed up the job but also ensure 100% precision and perfection due to the precision CNC machining process. This guarantees a flawless fit and finish every time, saving you time and effort while delivering superior performance and reliability.

Precision CNC machining guarantees outstanding durability and a perfect fit for our Billet 4 into 1 merge collectors. This meticulous process ensures that each collector meets the highest standards of quality, providing reliable performance and a precise fit every time.
