GrimmSpeed Uppipe - Subaru Models (inc. 2006-2014 WRX / 2004+ STI)

Spectral Performance proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

This is the GrimmSpeed Up-Pipe. This up-pipe has been designed to be a high-performance direct replacement for your factory up-pipe to add more power and performance. Over time, mileage, and heat cycles, the interior walls of your factory up-pipe can become brittle and come apart inside which blocks the flow path of the turbocharger. This will create a block in the power making your vehicle feel weak and underpowered. This can also cause premature wear on the turbocharger as it works harder to try and hit target boost. GrimmSpeed relieves this issue with the right solution with their example that is made using smooth bends that are combined using the best materials that will sustain years of abuse.
