Downpipes and Y Pipes

Check out our latest Downpipes and Y-Pipes from HKS, COBB Tuning, GrimmSpeed, Injen and Invidia.

Just like intakes, downpipes and Y-pipes are among the most popular modifications you can perform on a turbocharged vehicle. What are downpipes? Downpipes are the metal Lochness Monster that connects directly Read More to the turbocharger. The factory equipped downpipe on the majority of turbocharged vehicles are highly restrictive and must be replaced in order to achieve a certain boost or horsepower goal. The same circumstances are for vehicles equipped with a Y pipe. Some vehicles like the Nissan GTR are twin-turbocharged and will have a set of downpipes that connect to a Y-pipe or otherwise known as a mid pipe. 

So how do these downpipes create so much horsepower? They allow the turbo to breathe better, and make better use of the power they are capable of making. For example, with an upgraded intake you are allowing the turbo to inhale large volumes of air, whereas the downpipe removes the restrictions and allows the turbo to exhale much better. This results in horsepower gains, torque gains, reduced turbo lag, and more than likely an increase in throttle response.

But like the intake, in some makes and models, you cannot bolt a downpipe or Y-pipe on and call it a day. Some cars like the Subaru WRX or Mitsubishi Evolution and the Nissan GTR require a tune to safely run a downpipe. Usually, with a Subaru, you can risk hitting fuel cut, so you would need some sort of Engine Management such as the COBB Accessport and one of their many available off the shelf maps will be available for users to load and drive safely.
