If you're spending precious dollars to modify your turbo-equipped ride, it makes perfect sense that you would want to do everything possible to maximize exhaust flow for increased turbo efficiency. A larger-than-stock downpipe frees up exhaust gases and provides impressive power increases and faster turbo spooling, helping to reduce turbo lag, slightly increase boost pressure, and reduce exhaust gas temperature.
Once you increase boost in your turbo system, it's a good time to consider replacing the restrictive factory downpipe. An aftermarket downpipe offers a larger diameter and smoother bends than the original, resulting in what is often a substantial horsepower increase. Depending on the design, downpipes may also come equipped with integrated high-flow catalytic converters and/or exhaust diverters, which re-route wastegate gases for decreased exhaust turbulence.
Q: What does a down pipe do? Why buy a down pipe?
A: The factory catalytic converter assembly often chokes the exhaust system and prevents it from flowing at maximum velocity. In any turbocharged application a significant increase in horsepower and torque can be found by simply eliminating this restriction in the exhaust flow. Down pipes provide a larger diameter for turbocharged vehicles, providing better spooling times from the turbo and easier exhaust flow.

Q: Do down pipes only work on certain vehicles?
A: Down pipes are meant for turbocharged vehicles only.
