FD3S 4" Stainless Downpipe
The 4" is recommended for better low end / transient response on larger turbo setups. It mates perfectly with most turbos on the FD3S Long Tube Manifold. Built with the same quality as the manifolds; fully back purged, 304 stainless mandrel bend construction, perfectly straight sanded flanges, and both fit a stock location exhaust setup. A wideband O2 bung is already welded in place, and a high flow / quality flex bellow. Gasket and fasteners are included for stock exhaust connection.
Fits only LHD at the moment but it will be avalible for RHD soon
