If you’re looking to squeeze every bit of power out of your 2025+ BMW M5 G90, you might want to consider ditching that factory downpipe. Let’s be real: the stock catalytic converter is a major bottleneck. It's designed with this honeycomb structure that forces exhaust gases to squeeze through tiny openings, creating turbulence and slowing everything down. Not exactly what you want when you're trying to unleash the beast under the hood.

That’s where our Competition Series Catless Downpipe comes into play. By swapping out the factory setup, you’ll notice a serious boost in horsepower and torque. This isn’t just theory; you’ll feel the difference the moment you hit the gas. It’s all about getting that exhaust flow unrestricted, and our downpipe does just that.

We built this thing tough, using 100% 304 grade stainless steel, so you know it’s going to last. Every piece is mandrel bent for smooth transitions, and our in-house fabricators TIG weld everything to ensure top-notch quality. Plus, we CNC machine the V-Band flange from billet stainless steel, so it fits perfectly with your turbocharger. And don’t worry about the O2 sensor; it’s positioned exactly where it needs to be, retaining the factory donut flange design for a straightforward, bolt-on installation.

Whether you stick with the factory exhaust or go for something aftermarket, our downpipe fits like a glove. No compatibility headaches here. It comes standard with a brushed finish, but if you’re feeling fancy, you can opt for a mirror polish or even a high-temperature black thermal coating to keep those underhood temps down.

Now, for the tech specs: this setup features mandrel bent 3” piping for a smooth exhaust flow, which means better throttle response and quicker turbo spool-up times. You’ll notice that torque curve hitting faster and lasting longer, giving you that exhilarating feeling of power when you need it most. And rest assured, we've tested this on the track for durability, so it’s built to handle the heat.

We’ve included all the necessary hardware for a complete installation, and we back our product with a limited lifetime warranty because we believe in what we make.
