304L 2-inch stainless tubing prevents loss of heat energy and will not corrode like aluminized steel or 409 stainless
Larger bore (1.8" ID) internally shielded 304 stainless bellows, eliminates restrictive 1.3" ID OEM bellows maximizing exhaust energy to drive turbocharger
Smooth mandrel bends improve exhaust gas flow - tubing ID is not compromised
Increased turbo response with lower EGT's
User must have aftermarket downpipe, does not fit with OE Downpipe
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 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.
