This is Invidia’s Newest Downpipe, with a Divorced Wastegate that will separate the exhaust gas exiting the downpipe, creating a smoother exhaust flow, thus resulting in more HP and Torque.

Invidia’s downpipe is a great way to start adding Horse Power and Torque gains. This system was tested in turbo magazine. When combined with the cat-back section, HP gains were seen up to 60+ at the wheels with engine management.

The downpipe is constructed of 304 stainless steel with a large bell mouth, which will ensure longevity while enhancing power by freeing wastegate gases. 3″ mandrel bent and bolts up to any catback or stock unit.

This Downpipe is for use with 02-07 Subaru WRX and STI Manual and Automatic Transmissions.

This Downpipe has an extra O2 bung welded in for use with a Wideband O2 sensor.

Because this product replaces/removes an OEM emissions control device we must state that this catless downpipe is for offroad use only.
