Subaru Impreza WRX/STi Tubular Exhaust Manifold + 2.5″ Uppipe, EJ20, 92 to 05

Replacement tubular exhaust manifold for the Subaru Impreza WRX with the EJ20 engine

This manifold has 1.5″ ID runners which come together and go into a precat replacing 2.25″ ID uppipe.

Fits turbo cars made between 1992 and 2005, with the single inlet TD04 or TD05 turbo.

This is still an unequal length manifold so you will keep the unique sound of that boxer flat four.

The manifold has the ports for the lambda and temp sensors.

This part will increase power especially at higher RPM where the gases are able to flow better.

Comes complete with everything you can see in the picture, this can be very tight to the sump on some models and occasionally requires the sump to have a minor modification or you can just fit the twin scroll sump. It not essential but you can heat wrap the manifold for further performance gains.

Made from Stainless Steel
