The GTSPEC unequal length exhaust manifold & detachable uppipe for the 02-07 WRX & STI is the latest revision of their orginal 2-piece WRX & STI manifold kit. GTSPEC's revolutionary velocity chamber design and the high quality finish are unchanged on the new generation for optimal flow, performance, and looks. The velocity chamber equalizes exhaust gases before the turbo for fast spool and minimal turbulence. The GTSPEC WRX & STI manifold's flanges are completely redesigned top prevent warping and cracking. The header's 3-bolt uppipe flange creates an even distribution of pressure for optimal sealing. The GTSPEC WRX & STi header kit includes the manifold, uppipe, and necessary gaskets (manifold to block x 2, 3-bolt manifold to uppipe gasket, & uppipe to turbo gasket) for a direct bolt-on installation.

Fitment: 02-11 WRX, 04+ STi, & 05-09 LGT
