At ARTEC we have revolutionised the turbo manifold industry with our industry-leading SUS347 stainless steel investment cast manifolds.

All of our manifolds are engineered and designed from the ground up, CFD simulated, and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance and a beautiful smooth exterior finish.

Designed and tested in Australia, backed with a lifetime warranty.

One rule with ARTEC is that we don't just follow the pack. This is shown again with our EVO Dump pipe, Cast Outlet, or 02 Housing, (Different countries have different names for them). Virtually all the companies in the market (except for the new Tomei Version 2 Dump and front pipe) are designed to replace the original individual piece. This is a great concept for EVO tuning as it allows people on a budget to buy what they can when they can. We saw that 95% of the serious EVO guys and girls were changing both. So why make one work with the other and be restricted with the tiny original donut gasket/ with OEM dimensions. This is why we developed the ARTEC 3.5 Cast Outlet. We use a 3.5 V-Band on the outlet side for simple installation, as well as including a second 02 sensor mount for people wanting to run a wide band sensor without having to take parts off later and weld bits on which can quickly add up the cost. The other little feature we added was easy access to the lower nut, we have created enough space to use a ratchet spanner to do this up. You or your workshop/tuner will thank us later.

Once we had the 3.5 Cast Outlet finished, we could go ahead and join the dots up, and make the sections to create the first true production 3.5 EVO Turbo back exhaust.

With the addition of the new front pipe and cat delete, we have been able to allow people to have far great boost control by having less back pressure on the wastegate exit path. We suggest anyone upping the power and boost switch to an 18 psi or higher wastegate spring to aid in superior boost control.
