Subaru WRX & STI 2018-2019 Exhausts
When it comes to 2018 WRX exhausts it’s true to say you definitely have options. JDMuscle guarantees you’ll only find the best performance exhausts here with us. 2018 WRX exhausts can really help to bring your Subaru to life. The Tomei Expreme Ti Titanium cat back exhaust is perfect for those who are looking for the single outlet exhaust system. This system is meant to be very light to shed weight and is also a straight system to help increase airflow. For those pursuing a quad tip exhaust system, look no further. The Nameless Performance 3 inch quad exit axle back system is polished and crafted with mandrel bends. This system features laser cut flanges that will help to increase horsepower and torque as well as improve throttle response.
We know that 2018 WRX exhausts and 2019 STI exhausts are only complete if you start from the manifold which is why it’s in your best interest to install the Tomei unequal length exhaust manifold. This unequal manifold will greatly increase your exhaust efficiency and will improve turbine performance. Tomei’s unequal length manifold was designed to preserve the legendary boxer sound. Complete your 2018 WRX exhaust system with a Nameless Performance 3 inch midpipe. This mid pipe was designed to increase horsepower and torque because of its “Y” design which was constructed from a 3 inch primary pipe that exits out of 2 inch outlets. This has been shown to increase back pressure and has proven to improve torque ratings by 34 ft/lbs. Be sure to check out our 2018 WRX Trunk parts as well.
