Description

Material Selection

• First and foremost not all 304 Stainless steel is created equal. Walton carefully select the exact specification of the tube that we use. The use of a poor-quality tube can compromise the whole design. For instance, exhaust manifolds experience repeated high-temperature cycles. In these situations, we have seen poor tubing split along the seam.
• Walton design the head flanges in-house. However, they outsource the precision Fiber Laser Cutting. The use of more modern Fiber Laser cutting allows for increased accuracy over traditional laser cutting

Processes

• Where the manifold meets the exhaust ports, Walton Motorsport’s process is to push the tubing through the head flange and TIG weld each side. This process is followed by a selection of finishing tools. They do this to create a smooth port for the gasses to freely flow through. Consequently, this process dramatically increases the durability of the manifold, rather than using the traditional method of welding the tube to the face of the flange. Moreover, their approach also solves the problem of an oval port needing to transition smoothly to a round tube. The stubs process, in short, helps increase power through the improved flow.
• The centerpiece of the manifold is the in-house designed cast collector. Walton’s latest collector design features the highest wastegate flow they have ever achieved on a merge collector, all without compromising on power-reducing turbulence and high EGTs. This is achieved by sourcing exhaust gasses from a wider opening with the smoothest possible transitions. The casting process allows for a seamless design, preventing any break up of the collector and eliminating potentially harmful turbo and engine failures.

Lifetime Warranty

Bombproof? Walton haven’t found out yet. Their exhaust manifolds have been designed put up with some serious abuse though. Walton offer a lifetime warranty on their products as many do. However, we put a huge emphasis on the strength and durability of our products to stop them from failing. The biggest inconvenience when it comes to a failed manifold (providing none of it ends up inside your turbo or engine) is removing it for repair. By eliminating the failure in the first place, they can honestly say it would be extremely unlikely to experience a failure of Walton products. Consequently, they wouldn’t sleep well at night if their product failed and cost you a result.
