PERRIN 15-21 Subaru STI/15-25 WRX SS Dual Tip Axle Back Exhaust (Fits OE/AM Ctr Pipes)

With this PERRIN Axle Back Exhaust system, you get the muffler assembly and dual 4.5-inch slash-cut tips. This is designed to bolt directly onto your factory or aftermarket center exhaust pipe, making installation straightforward. It's built entirely from stainless steel, which means it's going to hold up well against road salt and moisture over time, keeping it looking good and functioning properly for years to come. The dual tip design gives your WRX or STI a more aggressive stance and a sportier exhaust note that's noticeable but not overwhelming.

The stainless steel construction isn't just about looks; it also helps keep the weight down compared to heavier, older exhaust materials. This axle-back system is specifically tuned to give you a more engaging sound when you accelerate, adding a bit of character to your driving experience. It's a popular choice for owners looking to get a bit more auditory feedback from their Subaru's boxer engine without needing to replace the entire exhaust system. The 4.5-inch tips provide a substantial visual upgrade, filling out the rear bumper area nicely.

When you're ready to install, you'll find that this axle-back setup is designed for a direct fit, meaning no welding or cutting is typically required. Just unbolt your old mufflers and bolt these on. It's a great way to personalize the sound and appearance of your 2015-2025 WRX or 2015-2021 STI, giving it that extra bit of flair and a more satisfying exhaust note.
