Description

Walton Motorsport Mazda 13b Exhaust Manifold (RX7 FD)

The Mazda RX7 FD 13b Exhaust Manifold is our first commercially available manifold for the triangle engine otherwise known as a Rotary (or Wankel)
There’s no shortage of Mazda 13b exhaust manifolds available. The construction methods we use set our product apart from the rivals.?

Mazda 13b Exhaust Manifold Construction

Material Selection

• First and foremost not all 304 Stainless steel is created equal. We carefully select the exact specification of the tube that we use. The use of 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 inhouse. 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

The Mazda 13b Manifold uses a divided T4 Turbo flange. As a result, this allows the manifold primary pipes to remain separate. This negates the need for a collector.

The process of back purging during welding provides a smoother internal weld. This improves gas flow. Therefore, more power.

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.?
