13B-T4-EX / 58540010 Artec 13B-REW T4 split pulse manifold for FD3S  *For competition (race) use ONLY. Check legality of aftermarket products with your local state, county, city authorities before purchasing. This unique design of this manifold with runner separation all the way to just before the wastegate valve face was a very complex manufacturing hurdle, but now it is avaliable.  By running a single wastegate you can also cut down on cost as well as an easier setup to thermal manage. This manifold was designed to accommodate the Garrett G40 turbo, which will leave you space for other smaller units. The 13B manifold also features wastegate machining to suit a Gen 5 Turbosmart 50mm Wastegate, though as you can see we have provided a cut line if you wish to run a 60mm for any reason. --- ARTEC's revolutionary turbo manifolds with industry leading SUS347 stainless steel investment cast construction, are now available through GReddy Performance Products. All Artec 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 optimized manifold with consistent performance, resistant to heat pooling and cracking, plus a beautiful smooth exterior finish.
