HIGH EFFICIENCY Don’t cook your engine bay! Keep heat where it needs to be – the turbocharger. Our log-style exhaust manifold is perfect for a responsive, efficient setup. To further improve spool, check out our Quick Spool Valve! EASY PIPING Our bottom mount design enables short downpipe routing without any tight bends. The Intercooler piping can be routed directly into the bumper. No need for cutting your chassis! DURABILITY Our manifolds are investment cast from SS304 with a wall thickness of 5mm – strong and reliable. NO BOOST CREEP Centered 44mm wastegate flange for convenient installation and high wastegate flow. TAPERED PORTS The ports are tapered to match the stock exhaust ports on the head. The taper can easily be removed. EGT SENSOR Your manifold will come with a 1/8″ NPT thread for mounting an EGT sensor. A stainless steel plug is included. NOTE For better fitment you should rotate your water neck by 180 degrees like shown in the picture. No additional parts are required. Some water necks have a tab which has to be cut off in order to be rotated. For better clearance around the compressor housing we recommend to upgrade your engine mounts, which you should do anyway when boosting your GE. The Turbocharger shown in the pictures is a BorgWarner S364-SXE. There is still plenty of space around it. Fits even with our Quick Spool Valve into a Lexus IS chassis.
