The downpipes that propelled our Alpina B7 to a record-setting 11.2 in the 1/4 mile are now available! The B7 is an amazing vehicle with incredible performance; however, we knew there was more. We took time investigating the areas with the most inefficiencies that would help bring this car to the next level. Quickly we focused on the exhaust flow. Naturally, the catalytic converters typically restrict flow, so we began there, we decided to go with 3.5” primaries to give the system enough area for thermal expansion post turbo. Enhancing the ability for the turbo to keep maximum shaft speed, boost quicker and help with transient turbo response. We eliminated as many unnecessary bends as possible to further assist with overall flow, and we finished off with a ceramic coating to protect nearby components from radiating heat and aid in the thermal pumping constructed from high-quality stainless steel to ensure durability and longevity with today’s high-performance standards
