The downpipe is the first section of the exhaust system after the turbocharger, and on most factory turbocharged vehicles it is also the single most restrictive exhaust component due to its large catalytic converter and tight mandrel bends. Turbocharged car enthusiasts who shop for aftermarket downpipes range from street-driven daily drivers looking for a bolt-on power and sound improvement to track-day and time attack builders prioritizing maximum flow on tuned builds with larger turbos. Upgrading the downpipe removes the primary restriction in the turbocharged exhaust path and can produce measurable gains in peak horsepower, turbo spool time, and exhaust note character when properly paired with an ECU calibration. Well-known platforms that benefit strongly from downpipe upgrades include the Subaru WRX and STI with the EJ205 and EJ257, the Volkswagen GTI EA888, Ford Mustang EcoBoost 2.3L, Mitsubishi Lancer Evolution 4B11T, and the BMW N54 and N55 engines.Popular UpgradesTop afterma...
