We have the perfect solution if you have ever built a turbo exhaust manifold or swapped the wastegate to a 38mm and were missing the flanges. Another common issue is that cheaper flanges warp from heat over time or even when welding onto a manifold/external wastegate pipe.

Our Exoracing weld-on wastegate flanges are crafted with the utmost attention to detail, utilising high-quality stainless steel and CNC machines to ensure precision. Designed explicitly for fabricators, at 11mm thick, our stainless steel flanges are less susceptible to warping than thin flanges.

Each of our expertly deburred weld-on exhaust flanges are simple to weld, making them ideal for constructing or replacing a turbo and wastegate system.

We include a pair of stainless steel wastegate gaskets to get you up and running with your new wastegate installation as soon as possible.

One wastegate flange featured tapped threads, while the other boasts a wider bolt hole for effortless removal. With our Exoracing wastegate flanges, you can trust that you are getting the best quality and functionality for all your fabrication needs.

We now offer a lifetime warranty on our weld-on wastegate flange kit as we are incredibly confident in our stainless steel flanges and want to provide a risk-free buying experience.

Please follow the steps below to correctly install your new 38mm wastegate flange and gasket kit. Please ask a professional to install it if you are unsure of anything in this guide or are not confident or safe when welding.

1. First, remove the manifold or screamer you are welding from the car and ensure you have thoroughly cleaned the wastegate flanges and surface metal you are welding to for the best possible weld.
2. Weld the flanges to either the manifold, screamer/downpipe or both sides, ensuring you get them the correct way around. The tapped wastegate flange always goes on the manifold, and the untapped flange will go on the wastegate outlet side.
3. Once you are happy they are welded correctly and have cooled down, install them back onto the car using the supplied gaskets between the wastegate inlet and outlet, and torque the bolts to factory specifications.
4. After you are confident there are no boost leaks and a few heat cycles have passed, please ensure to retighten the bolts, as they often become loose due to heat.
5. You are all done! Please tag us on any of our social media platforms with any photos you take of your setup, as we would love to see them.

• The tapped flange has been designed for the manifold side.
• The untapped flange has been designed for the wastegate side.
• Professional Installation is highly recommended.
• If you are welding the flanges yourself, please ensure both welding surfaces are as clean as possible for the best weld.
• Please retorque the wastegate inlet and outlet bolts after a few heat cycles.
