PLM - SUB - MID - 2015 - NON. The PLM Private Label Mfg. Power Driven 3 - inch NON - Resonated Midpipe Kit for Subaru WRX STI is designed to boost horsepower, improve exhaust flow, increase power and torque, and create a more aggressive sound, all without reducing your ride height. With CNC mandrel bending, the tubing maintains a consistent diameter throughout the bend, ensuring a perfect fit and better exhaust gas flow. This system features a straight pipe to remove the resonator, stainless steel flanges, and is a direct fit for our muffler deletes / axlebacks (not included). Finish it off with a straight - through, low - restriction racing muffler for unobstructed flow. Note: This product is not compatible with SPT Axleback exhaust systems. Key features include stainless steel construction, a one - year limited warranty, replacement grade 8 nuts and bolts, a machined CNC - ed flange, precision CNC mandrel bending, a dolphin tip muffler, a 3 - inch split to 2.5 - inch design, included gaskets and bolts, a non - resonated version, and professional Tig welding and assembly. It bolts directly onto PLM Axleback for easy installation (may not fit other axleback systems).
Using this midpipe is quite straightforward. First, make sure your vehicle is the Subaru WRX or STI from 2015 - 2021. It's designed to bolt directly onto PLM Axleback, so find a suitable place to work on your car and use the included gaskets and bolts for installation. Remember, this product may not fit other axleback systems, so stick to PLM Axleback for the best results. Also, it won't work with SPT Axleback exhaust systems, so don't try to install it with those. As for maintenance, since it's made of stainless steel, it's quite durable. But over time, you can clean it with a mild stainless - steel cleaner to keep it looking good. Check the nuts and bolts periodically to make sure they're tight. If you notice any unusual noises or performance issues, it might be a good idea to have it inspected by a professional.
