Artec have revolutionised the turbo manifold industry with a unique direct replacement cast stainless turbo manifold to suit the Mitsubishi Ralliart 4B11 engine.
After scanning and extensively testing the factory 4B11 Ralliart turbo manifold, our conclusion is that only 3 out of the 4 runners reach the collector and 2 of the runners meet just before the turbo flange area. This exposes the factory item to pre-emptive failure as the extreme heat collects in such a small diameter of pipe with twice the exhaust gases it would normally experience. All this additional heat in this area also causes the metal to expand which gives way to movement and leaves it prone to cracking (a common problem).
Artec manifolds are unique as they are tuned and CAD simulated to achieve maximum flow and heat dispersion, whilst at the same time removing restrictions caused by tight radius bends in the factory manifold which therefor increases exhaust gas flow exponentially. Say goodbye to heat pooling, cracked manifolds and unequal exhaust gas distribution and say hello to a product which is designed and tested in Australia and is backed by a lifetime warranty!
All Artec manifolds are guaranteed to fit your engine bay and auxiliaries without headache or fuss and are designed to be installed in approximately 10 minutes. The bolt locations are easily accessible as the cast was designed around them for ease of installation and accessibility. Artec stainless manifolds are the unrivalled in their simplicity and efficiency!
