What type of welding rod is recommended for these mild steel flanges?

Vibrant Performance suggests using 309L welding rod when mating these mild steel flanges to 304 stainless steel tubing. This helps create a strong and reliable weld between the two different materials.

What does 'optimized port sizing' mean for these flanges?

The port openings on these flanges are shaped to match common exhaust tubing sizes, specifically standard wall round tubing or Schedule 10 weld fittings. This makes it easier to align and weld your custom exhaust pipes to the flange.

Are these flanges sold individually or as a set?

These exhaust manifold flanges are sold as a pair, meaning you receive two flanges in the package. This is convenient for fabricating or replacing both sides of an exhaust manifold.

Product Details

Starting with a solid 1/2 inch thick piece of HRPO mild steel, these exhaust manifold flanges from Vibrant Performance are built to handle custom exhaust fabrication. The port sizing is specifically optimized to work well with standard wall round tubing or Schedule 10 weld fittings, making it easier to get a clean, strong weld when you're building a custom exhaust system for a wide range of Audi vehicles, including models like the A4, A6, and S4.

These flanges are laser cut for accuracy, ensuring a flat mating surface for your cylinder heads. While they are made of mild steel, Vibrant suggests using 309L welding rod if you're joining them to 304 stainless steel tubing, which is a good practice for creating a durable bond between dissimilar metals. This pair of flanges is a well-built starting point for anyone looking to fabricate or replace exhaust manifolds on their Audi 2.7T or 3.0 engine.
