Walton Motorsport Mitsubishi Bottom Mount V-Band Exhaust Manifold Lancer Evolution 4 IV 5 V 6 VI 7 VII 8 VIII 9 IX 4G63T

Looking for an EVO Manifold? Well, you probably dream of a few more ponies under the bonnet. To make use of the awesome handling chassis. The Bottom mount manifold from Walton Motorsport is designed to mount any of the Garrett GTX30, GTX35, and G25/G30 turbos. When used with a V-band Housing. The manifold is also available with a Precision or Tial/GBT V Band Fitting

There’s no shortage of Mitsubishi Evo 4-9 exhaust manifolds available. The construction methods we use set our product apart from our rivals. 

MITSUBISHI EVO 4-9 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. 

MITSUBISHI EVO 4-9 EXHAUST MANIFOLD FEATURES

Carefully selected 304 Stainless steel tube. Working to eliminate the risk of material failure.

Fully Purged welded. Subsequently improving gas flow leading to increases in power and lowered response times.

Ported Merge Collector Welded Internally and Externally. Resulting in high strength, durability and turbo lifespan.

Curved wastegate port design developed with leading engine tuners to allow high control and remove boost creep.

Fully Smoothed Head Ports designed to optimize gas flow. As a result, providing an increase in power and lowered response times.

Optimized for use with Turbosmart Gen-V Hypergate 45 Wastegates.
