Overview:

The Borla Rear Section Exhaust System is a precision-engineered upgrade designed specifically for the Scion FR-S (2013–2016), Toyota 86 (2017–2020), and Subaru BRZ (2013–2020). This rear section exhaust offers an excellent alternative to a full cat-back system by replacing the factory rear muffler and tip assembly while retaining the factory mid-pipe. It is ideal for enthusiasts seeking a more aggressive exhaust tone and improved performance without the complexity of a complete exhaust overhaul.

Crafted to enhance both sound and power, the Borla 11839 rear section exhaust delivers a refined yet sporty exhaust note that complements the sporty character of these popular sports coupes. It is perfect for drivers who want to elevate their vehicle’s auditory presence and exhaust flow with a direct-fit, bolt-on solution.

Key Features:

This rear section exhaust system incorporates advanced design elements and quality materials to ensure durability, performance, and style:

• Direct bolt-on fitment to the factory mid-pipe for easy installation
• 2.5-inch inlet piping transitioning to dual 2-inch exit pipes for optimized exhaust flow
• 4.5-inch single round rolled angle-cut phantom tips for a clean, aggressive look
• Constructed from aircraft-quality austenitic stainless steel for corrosion resistance and longevity
• Designed to reduce back-pressure, enhancing engine efficiency and throttle response
• Produces a more aggressive and sporty exhaust note without excessive drone
• Compatible with stock and aftermarket components for flexible integration

Construction & Design:

Borla’s rear section exhaust system is built from premium austenitic stainless steel, known for its exceptional resistance to rust and corrosion. This material choice ensures the exhaust maintains its appearance and structural integrity over time, even under harsh driving conditions. The system features precision-welded joints and mandrel-bent piping to maintain consistent diameter and smooth exhaust gas flow.

The design includes a 2.5-inch inlet pipe that smoothly transitions into dual 2-inch exit pipes, which helps to decrease exhaust back-pressure and increase velocity. The 4.5-inch rolled angle-cut phantom tips provide a subtle yet aggressive visual upgrade that complements the sporty styling of the FR-S, 86, and BRZ.

Performance & Sound

By replacing the restrictive factory rear muffler and tip assembly, this Borla rear section exhaust improves exhaust gas evacuation, resulting in decreased back-pressure and enhanced engine breathing. This translates to improved throttle response and potential gains in power delivery.

The exhaust note is notably more aggressive and sporty compared to stock, delivering a deep, refined tone that enhances the driving experience without overwhelming cabin noise or drone during cruising. This balance makes it suitable for both spirited driving and daily use.

Installation & Fitment:

The Borla Rear Section Exhaust System is designed for a direct bolt-on installation, requiring no modifications to the factory mid-pipe or other exhaust components. It replaces the factory rear muffler and tip assembly, making installation straightforward and accessible for enthusiasts with basic mechanical skills or professional installers.

All necessary mounting points align with factory locations, ensuring a secure fit and proper exhaust alignment. This system is compatible with the stock exhaust setup and can be integrated seamlessly with other aftermarket components.
