Features & Product Details
RallySport Direct proudly carries a great selection of quality automotive performance upgrades and accessories brought to you by GrimmSpeed.
This is GrimmSpeed's Coated 3-bolt Up-Pipe. Over time and mileage, the factory up-pipe can be a roadblock to your performance. In some cases, pieces of the interior of the factory up-pipe car break apart which can block the flow path of the turbocharger. This will make the turbocharger work harder to make boost, and it can cause premature wear to the turbo while making the car feel sluggish overall. Because of these reasons, enthusiasts like to upgrade the rest of the exhaust system at times, overlooking the up-pipe. If you have purchased an aftermarket 3-bolt header in the process, this is the up-pipe you will need.
The GrimmSpeed unit is the result of tireless design and engineering that optimizes the performance out of your EJ. Using their in-house FARO Arm along with the latest Solidworks CAD Software, GrimmSpeed was able to achieve the most precise and best fitting up-pipe for you're aftermarket 3-bolt header on the market. After reverse-engineering some 3-bolt header layouts, they determined the best range of nest fitments for their up-pipe which delivers leak-free performance.
