Tomioka Unequal Length Headers w/ Uppipe WRX / STI 2002-2021 Subaru EJ Turbo Models

Part #: TR - ES1000. These TR all - stainless - steel single - scroll unequal - length exhaust manifolds are perfect for Classic GC8/GF8 and New Age WRX STI GDA GDB Type A - B. They feature a lost - wax finish with 4 - 1 connectors and a smooth inner surface, which greatly enhances exhaust flow. The 3 - bolts flange design on the up - pipe ensures a stable connection and prevents air leakage. A 45mm pipe size further improves exhaust flow. What's included: an exhaust manifold, an up pipe, turbo gaskets, a 50' x 2in exhaust wrap, and hardware kits. Notes: Some 2002 - 2005 WRX models require a 2.5l STI oil pan, and 2006 - 2007 WRX models need an STI oil cooler and an STI oil pan.

Using this Tomioka exhaust header and uppipe system is straightforward. First, make sure to check if your vehicle matches the specified models (WRX / STI 2002 - 2021 Subaru EJ Turbo). If you have a 2002 - 2005 WRX, some models may need a 2.5l STI oil pan, and 2006 - 2007 WRX models require an STI oil cooler and pan. When installing, use the included hardware kits to connect the exhaust manifold, up pipe, and turbo gaskets firmly. Wrap the 50' x 2in exhaust wrap around the pipes as needed. For maintenance, regularly check the connections to ensure they are tight and there is no air leakage. If you notice any damage to the stainless - steel parts, it's best to replace them promptly to keep the exhaust flow efficient.
