About this part

Invidia's R400 cat-back exhaust (HS08STI5GM4ST) is built for the 2008–2014 STI hatch. Piping is SS304 stainless at 76mm diameter and 1.5mm thickness, finishing in titanium-coloured quad straight-cut tips. Invidia quotes a 17hp, 26ft-lb torque gain from the system's twin independent muffler canisters, smaller and less baffled than a single large unit, which is where the added volume and sharper note come from.

Fitment

Confirmed for the chassis below. We list a chassis only where the part is on one of our cars or on the manufacturer’s own application list.
