Tomei Expreme Exhaust Manifold SR20DET

Description

Tomei EXPREME exhaust manifold is now available for SR20 owners who want a performance upgraded from the genuine exhaust manifold. No special modifications are needed to fit the standard turbo.  TOMEI EXPREMEs exhaust manifold for the SR20 is designed with a partition plate inside the 1st & 4th turbine side ports as the 2nd & 3rd are divided for the exhaust ports. The sequential ignition firing order of the SR20 (1-3-4-2) can cause exhaust interference. The exhaust is discharged from both left and right of the partition plate and can cause to happen where the pipes all merge together. Now TOMEI has found the best possible exhaust flow.

this manifold fits all RWD SR20DET models (S13, S14 & S15) not intended for FWD SR20’s
