Catback Exhaust - 4" Muffler - 4" Double Wall Tips

The Nameless Performance 4” muffled catback is one of the most popular exhaust options for the VB WRX, offering a balanced mix of aggressive tone and daily drivability. Built from high-quality stainless steel, this system features a true 3” mandrel-bent design for improved exhaust flow and performance. The 4” muffler variant is specifically designed to reduce drone while still delivering a deep, refined exhaust note—making it ideal for daily drivers who want sound without excessive cabin noise. Compared to muffler deletes or smaller mufflers, this setup provides a deeper tone with less rasp and highway drone, while still opening up nicely under throttle. The 4” double wall tips offer a clean, premium look that fills out the rear bumper well and resists discoloration over time. Overall, this is a go-to choice for WRX owners wanting a high-quality, bolt-on exhaust that enhances sound and aesthetics without sacrificing comfort.
