REDSTAR performance downpipes for the new 2018- Audi B9 RS4 / RS5 with Porsche twin-turbo 2.9 engine. Our downpipes utilize big bore design with smooth transitions for maximum flow efficiency. Long cones used to reduce the OEM 127mm turbo flanges to 89mm main diameter, which then goes down with second transition to 76mm lower 3-bolt flanges.
You buy directly from the manufacturer and all the products 100% handmade in Russia. Not just another relabeled China/Taiwan stuff.
We don't compromise on quality! No mild steel flanges, no weak clamp joints, no other cost reduction tricks.
Free flow is our priority! No steps and restrictive areas, only smooth transitions, bigger diameters, and optimized design.
Our welds and whole craftsmanship better than most of the competitors. Pictures speak for themselves.
5-year warranty against any defects given to the original owner.
We offer WORLDWIDE shipping via EMS Express (USPS Priority Mail International) from Russia. It usually takes 8-18 days to any destination.
