MagnaFlow Street Series Cat-Back Exhaust System for 2014-2024 Infiniti Q50, Stainless Steel

If you're looking to give your Infiniti Q50 a serious boost, the Street Series Stainless Cat-Back System is a solid choice. I’ve had my hands on this system for a while now, and I can confidently say it’s a game changer. The straight-through muffler design really opens up the exhaust flow, which means you're not just getting better sound—you're also unlocking some extra horsepower. It's like letting your car breathe freely for the first time.

Why It Stands Out

This isn’t just any exhaust system. The polished stainless steel construction gives it a sleek look that’s hard to ignore, and the 4.5-inch tips? They’re not just for show; they’re designed to enhance the sound and performance. Plus, the dual split rear exit adds a sporty flair that makes the rear of your Q50 look sharp.

Installation is pretty straightforward, thanks to the bolt-on inlet connection. You won’t need a degree in mechanical engineering to get this thing set up. Just grab some basic tools, and you’re good to go. The main piping diameter is 2.5 inches, which is perfect for maintaining that aggressive tone while keeping the interior noise comfortable for daily driving.

The sound? It’s a perfect balance. You get that performance growl when you step on the gas, but it doesn’t drone on during your daily commute. It’s just the right amount of presence without being obnoxious. If you’re after a system that delivers both power and a refined sound, this is it.

Fitment

This exhaust system fits Infiniti Q50 models from 2014 to 2024, so if you’ve got one of those, you’re in luck. Overall, the Street Series Cat-Back Performance Exhaust System from MagnaFlow has transformed my driving experience, and I think it could do the same for you.
