Downpipe Exhaust for 2008-2018 Nissan 370z Infiniti G37 | SPELAB

For enthusiasts looking for the highest possible exhaust flow from their vehicles, removing the factory catalytic converters in favor of 2.5" diameter race or "test" pipes is the most efficient upgrade available.

What Does A Downpipe Do?

The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.

By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.
