If you're looking to enhance your Subaru's performance, upgrading to a high-quality aftermarket up pipe is a must. The GrimmSpeed Up Pipe stands out as one of the best options available, engineered specifically for the Subaru EJ-Series turbo engines. This part is designed to maximize exhaust flow and minimize turbo lag, making it a top choice for enthusiasts who demand performance.
Using advanced technology, including an in-house FARO Arm and Solidworks CAD software, GrimmSpeed ensures that this up pipe fits perfectly on your vehicle. Many OEM exhaust manifold pieces can vary, leading to potential fitment issues. By reverse-engineering countless OEM parts, GrimmSpeed has created an up pipe that guarantees leak-free flanges and a perfect fit every time.
Crafted from the finest local materials, the GrimmSpeed Up Pipe features:
Each pipe is hand-welded both inside and outside the flange to ensure a robust connection and optimal flow characteristics. This meticulous fabrication process is carried out by certified welders, ensuring that your up pipe can handle whatever you throw at it.
When tested on a flow bench at 28 Inch WC, the GrimmSpeed Up Pipe outperforms OEM options significantly:
This translates to a quicker spool-up time of 300-400 RPM, giving you more immediate power when you need it.
The GrimmSpeed Up Pipe is designed to fit the following Subaru models:
Subaru WRX owners have noted, "After installing the GrimmSpeed Up Pipe on my 2011 WRX, I immediately felt the difference. The turbo spools up faster, and the sound is incredible!" Another Subaru Forester XT owner shared, "This up pipe fit perfectly and has really improved my low-end torque. I’m thrilled with the performance boost!"
Upgrade your Subaru with the GrimmSpeed Up Pipe and experience the difference in performance and reliability. It's a smart investment for any serious enthusiast.
