Invidia 15+ Subaru WRX/STI Single N1 Stainless Steel Tip Cat-back Exhaust

This Invidia N1 cat-back exhaust system is what you get when you order the HS15SW4GTP part number: the complete cat-back assembly, ready to bolt onto your 2015 or 2016 Subaru WRX or WRX STI. It replaces the factory exhaust from the catalytic converter back, giving your car a more aggressive sound and a sportier look with its single N1-style stainless steel tip. This system is designed to enhance the exhaust note without being overly raspy or droney, making it a popular choice for daily drivers who want a bit more character from their boxer engine.

Constructed from durable stainless steel, this cat-back is built to handle the elements and resist corrosion over time. The N1 muffler is engineered for a balance of performance and sound, offering a noticeable improvement in exhaust tone that’s deeper and more pronounced than stock, especially under acceleration. The single-tip design contributes to a cleaner, more focused aesthetic, and the stainless steel tip itself is polished to a shine, adding a touch of visual flair to the rear of your WRX. Installation is designed to be a direct bolt-on replacement for the factory system, meaning no welding or cutting is typically required, simplifying the process for most DIYers.

When installing this system, it's a good idea to have a friend help out, as exhaust components can be a bit unwieldy. Make sure to check the manufacturer's instructions for any specific torque recommendations or hardware requirements. This cat-back exhaust is a solid option for WRX owners looking to upgrade their car's sound and appearance while maintaining a well-built, reliable exhaust system.
