Invidia's downpipe is a great way to start
adding Horse Power and Torque. This system was tested in Turbo Magazine,
they found that 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
exhaust flow. 3" mandrel bent and bolts up to any stock replacement
catback or stock unit. This downpipe also has an extra oxygen sensor
bung welded in so you can install a wideband oxygen sensor and keep the
stock one intact. It comes with a plug installed so you don't have to
worry about not having one.
Because this product replaces/removes an OEM emissions control device we
must state that this catless downpipe is for off-road use only.
