If you're looking to really wake up your BMW M5 (G90) and unleash some serious power, let me tell you about our Competition Series Catless Downpipe. You know, factory exhaust systems can be like a chokehold on your car's performance, especially if you’ve got a turbocharged engine. The stock catalytic converter is a major bottleneck, thanks to its honeycomb design that makes exhaust gases fight their way through. This not only slows things down but also creates turbulence, which is the last thing you want when you're trying to maximize horsepower and torque.

Swapping out that factory downpipe for our Catless version is a game changer. The moment you hit the gas, you’ll notice the difference. Our downpipes are crafted from 100% 304 grade stainless steel, so you know they’re built to last. Each piece is mandrel bent and TIG welded right here in the USA by our skilled fabricators. We’ve even replicated the factory turbocharger’s 3.5" V-Band flange with precision CNC machining, ensuring a perfect fit every time. Plus, the O2 sensor is positioned exactly where it should be, so you won’t have any compatibility headaches.

One of the cool things about our downpipes is that they fit seamlessly with both the factory exhaust system and any aftermarket setups you might have. No fuss, no muss—just bolt it on and go. And if you’re into aesthetics, you can choose between a brushed finish or a mirror polish to match your ride. We even offer a high-temperature black thermal coating to help keep those underhood temps down.

Now, let’s talk performance. With our Competition Series Catless Downpipes, you’re looking at higher max horsepower and a torque curve that hits harder and faster. Throttle response is sharper, and turbo spool-up times are quicker, giving you that exhilarating feel every time you accelerate. And don’t worry about durability; these downpipes are track-tested to ensure they can handle whatever you throw at them.

Installation is straightforward, too. We include all the hardware you’ll need, and with a limited lifetime warranty, you can ride with confidence. So if you’re ready to take your 2025+ BMW M5 to the next level, our Catless Primary Downpipes are the way to go. Trust me, your car will thank you.
