ISR Performance 2014+ Infiniti Q50 ST Series Exhaust

This is the ISR Performance ST Series cat-back exhaust system specifically made for the 2014 and newer Infiniti Q50. A cat-back system replaces the factory exhaust from the catalytic converter back, including the mufflers and exhaust tips. It's designed to change the sound and flow characteristics of your Q50's exhaust system.

The ST Series is built from durable 304 stainless steel, which is known for its resistance to corrosion and its ability to handle high temperatures. This material choice means the exhaust should hold up well over time, even with daily driving. The system features a dual-muffler design, aiming for a more aggressive and deeper exhaust note compared to the stock setup. The piping is 3 inches in diameter, which is larger than the factory piping, allowing for improved exhaust gas flow. This can lead to a more responsive feel from the engine, especially at higher RPMs, and a noticeable change in the car's sound under acceleration.

When installing this cat-back system, you'll typically find it's a direct bolt-on affair, meaning no welding or cutting is usually required. It's designed to bolt up to the factory catalytic converter flange. You'll want to ensure you have the necessary hardware, like new exhaust gaskets for the connection to the catalytic converter, and potentially new hangers if your old ones are worn out. The result is a more pronounced exhaust tone that many enthusiasts prefer over the quieter factory sound.
