Product Description

Love the idea of swapping out your supercharger for the Garrett GTX2867 Turbo? You are in luck as our Manifold is designed for just that. The MINI R53 makes an awesome track-day car, but is lacking in the boost department. Strap that little turbo onto your engine to increase the excitement!

There’s no shortage of MINI R53 exhaust manifolds available. What sets the Walton Motorsport version apart from the competition is our construction methods.


    • 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 waterjet cutting. We use waterjet cutting as it results in a more accurate cut over traditional laser cutting
  • Processes

  • Where the manifold meets the exhaust ports, Walton Motorsports 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 greatly increases the durability of the manifold. Rather than using the traditional method of welding the tube to the face of the flange. Moreover, our method is where we also face 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 collector we use is a custom-designed merge collector. We proudly design and build in house. This results, in allowing us to add some features to set it apart from the competition. The first step is to TIG weld the seams inside the collector. Our fabricators then turn their attention to the outside of the collector. They TIG Weld the seams from this direction. The next step is to port the inside of the collector back to a smooth point. Subsequently, this improves gas flow and adds a large amount of strength. Without welding the inside of the collector there is a danger of small fragments breaking off at the high temperatures. These fragments will then make their way through your expensive turbo. We don’t need to tell you how bad that can be.

About Walton Motorsport

Walton Motorsport

Walton Motorsport was created by Mike Walton who began fabricating custom-built exhausts for a world-leading exhaust specialist, working on everything from classic rally cars through to LeMans cars. A move to Formula 1 then brought about new challenges, making epic exhaust systems for a multiple championship-winning Formula 1 team - nowhere else is such insane attention to detail and extreme quality control so paramount. With this wealth of experience and knowledge from the pinnacle of motorsport behind him, Mike decided to follow his true passion for drifting and set up on his own, now creating bespoke exhausts and manifolds for a whole host of high-performance road and competition cars including JDM legends and BMW thoroughbreds.
