Subaru Impreza WRX/STi Tubular Exhaust Twinscroll Manifold + 2.5″ Uppipe, 07 onwards

Replacement tubular exhaust manifold for the Subaru Impreza WRX with the EJ20/25 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 after 2007, with the twinscroll inlet BV37 turbo.

Can also be used on the earlier cars if you want to convert to the twinscroll turbo, you will need to change the sump and the downpipe at the same time to match the turbo. 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.

Made from Stainless Steel
