Replaces the factory exhaust up-pipes (exhaust manifold to the turbo) which are prone to leakage due to the deterioration. BD up-pipes are designed to minimize restriction to the turbo utilizing internally shielded expansion bellows .The turbo Y-adapter is made from high-silicon ductile iron. The BD up-pipes are a durable, longer-life replacement for this common problem and are perfect as an upgrade while performing other engine or transmission repairs.
