Tomei Expreme exhaust manifolds are designed with the shortest runners possible for the quickest turbo response. To minimize exhaust interference between cylinders at high rpms (due to its non-equal length design), the Tomei manifolds feature individual runners and a divider on the 1st/3rd and 2nd/4th ports on the collector. This allows Tomei to achieve a good balance between high rpm power and quick response.
Designed as a stock replacement manifold, will work with stock or aftermarket turbos that fit in the stock location.
Supplied with gaskets, hardware and a roll of exhaust wrap.
Large diameter turbo outlet pipe.
This upgraded actuator raises base boost to 14-18psi, and provides better boost control and response for running high boost (from 15-25psi). This actuator features a billet aluminum housing with a piston design. The internal spring can be changed for higher or lower base boost.
Fits the S15 turbo, can be easily fitted tomost internal wastegate T25/28 turbos.
