• 2008–2021 Subaru | WRX STI
• 2011–2021 Subaru | WRX

Ever feel like you’re just humming along in the crowd when you want to really play the song of your people? Many of our customers have wanted more sound from their existing Invidia Q300, R400 Gemini, or N1 exhaust setups without the hassle of swapping entire systems. That’s why we offer the Nameless Performance Muffler Delete Axleback—a simple upgrade that lets you unlock more aggressive sound while retaining your existing exhaust. Now you get two sound options that swap out with ease.

Key Features:

• Bolt-up fitment with factory-style flanges and hangers for direct replacement

• 3.5" polished single wall tips with mirror-polished finish

• CNC mandrel bent tubing ensures smooth flow and precise fit

• 100% T304 stainless steel construction, precision fabricated and hand TIG welded

• Solid hanger bars for stable mounting and durability

Benefits & Performance Gains:

• Dramatically enhances exhaust tone across the powerband by removing restrictive mufflers

• Frees up exhaust flow, improving throttle response and exhaust note feedback

• Lightweight design saves approximately 25 pounds over factory muffler setups

• Gains of 8-12 ft-lbs torque on STI and 6-8 ft-lbs on WRX models typically observed

• Offers a more engaging and aggressive driving experience without replacing the entire exhaust

Installation & Hardware:

• Simple install with basic hand tools—remove four bolts and hanger bushings from the factory muffler

• Hang the axleback from factory hanger bushings and bolt to the existing midpipe (compatible with Q300, R400 Gemini, and N1 midpipes)
