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.

304 stainless steel precision cast mounting flanges eliminate exhaust
tubing blowouts and ensures correct fitment
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
