ISR Performance ST Exhaust - Infiniti Q60

If you're looking to give your Infiniti Q60 a more aggressive sound and improved exhaust flow, the ISR Performance ST cat-back exhaust system is a solid option. This system replaces the factory mufflers and piping from the catalytic converter back, changing the tone and allowing the engine to breathe a bit easier. It's designed to bolt directly onto your existing exhaust hangers, making installation more straightforward than a full custom exhaust.

The ST series from ISR Performance is known for its straight-through muffler design, which helps reduce backpressure and lets the engine's natural sound come through more clearly. This means you'll get a deeper, sportier exhaust note without excessive drone at cruising speeds, which is a common complaint with some aftermarket systems. The piping is constructed from durable stainless steel, which holds up well against corrosion and the elements, ensuring this exhaust will last for a long time on your Q60. The system is designed to fit the Q60 chassis, meaning it should align properly with your factory exhaust hangers and clear the undercarriage without issue.

When installing this cat-back system, you'll typically need basic hand tools and possibly some exhaust hanger lubricant to help ease the removal of the old system and the installation of the new one. It's a popular choice for owners who want a noticeable change in their car's sound and a slight improvement in exhaust efficiency without going to an extreme setup. You'll likely notice a more satisfying rumble on acceleration and a cleaner exhaust note overall.
