Description
Walton Motorsport Nissan SR20 Exhaust Manifold
The very first product produced by Walton Motorsport was the top-mount Nissan SR20 Manifold. Huge numbers of the SR20 Exhaust Manifold have sold since the original to people all over the world. Throughout the years Walton Motorsport has worked to refine the design. As a result, this manifold is what is regarded to be the best SR20 manifold on the market today.
There’s no shortage of Nissan SR20 exhaust manifolds available. The construction methods we use set our product apart from our rivals.?
Nissan SR20 Exhaust Manifold Construction
Material Selection
- First and foremost not all 304 Stainless steel is created equal. We carefully select the exact specifications 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.
- We design the head flanges in-house. However, we 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. We 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, our 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 our in-house designed cast collector. Our latest collector design features the highest wastegate flow we 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? We haven’t found out yet. Walton Motorsport has designed the manifolds to put up with some serious abuse though. We offer a lifetime warranty on our 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, we can honestly say it would be extremely unlikely to experience a failure of our products. Consequently, We wouldn’t sleep well at night if our product failed and cost you a result.?
