Tomioka 3 Bolt Up pipe Subaru WRX / STI / Legacy GT / Forester XT EJ Models

Part #: TR - ES1012. The Tomioka Racing Uppipe is crafted from top - notch SUS304 stainless steel tubing. It's polished to a mirror - like finish and comes with a threaded Exhaust Gas Temperature (EGT) bung for stock sensors. With a 3 - Bolt to 3/5 - Bolt configuration, it's a breeze to install and fits perfectly. This uppipe is designed for turbo system upgrades and can handle the high exhaust gas temperatures of aftermarket systems. Its precise stainless - steel construction means no need for flex joint sections, ensuring a correct fit. The high - quality welding guarantees endless reliability and horsepower increases. Each flange is seamlessly welded to the piping, creating a smooth transition between the lower manifold, uppipe, and turbocharger, preventing exhaust flow from getting trapped. With one of the largest internal piping diameters on the market, it boosts mid - range to high - end horsepower thanks to improved exhaust flow. The 3 - bolt system has a 2' diameter from the uppipe to the turbo and a 2.3' diameter from the uppipe to the manifold. Application details: 2002 - 2004 WRX comes with a stock EGT Sensor. 2004 - 2014 WRX and 2004 - 2019 STi don't include an EGT Sensor (bung bypassed with a threaded cap). Other applications have a threaded plug to bypass the EGT bung. All installation hardware is included. Please specify your vehicle's year, make, and model at purchase.

Using the Tomioka Racing 3 - Bolt Uppipe is straightforward. First, make sure you've specified your vehicle's year, make, and model when purchasing as this will ensure you get the right fit. All the necessary installation hardware comes with the product. Just follow the normal installation steps for an exhaust uppipe. When it comes to maintenance, keep an eye on the welding and flanges. Since it's made of high - quality stainless steel, it's quite durable, but you can clean it occasionally with a mild stainless - steel cleaner to keep its mirror - like finish. One important thing to note is that depending on your vehicle model, the EGT sensor situation varies. For 2002 - 2004 WRX, you have a stock EGT sensor. For 2004 - 2014 WRX and 2004 - 2019 STi, the EGT bung is bypassed with a threaded cap. Other models use a threaded plug. Don't try to modify these setups without proper knowledge as it may affect the performance of your vehicle.
