If you’re looking to really unleash the potential of your 2025+ BMW M5 (G90), you might want to take a hard look at our Competition Series Catless Secondary Downpipes. Let’s be real—factory exhaust systems can be a bit of a bottleneck, especially when it comes to turbocharged engines. The stock setup has a couple of primary and secondary catalytic converters that just choke off the power. Those honeycomb structures in the factory catalytic converter? They’re like a traffic jam for your exhaust flow, creating turbulence and slowing everything down. Swap that out, and you’ll feel a noticeable boost in horsepower and torque right away.

Now, what makes our downpipes stand out? For starters, they’re crafted from 100% 304 grade stainless steel, so you know they’re built to last. We use mandrel-bent piping, which means smoother transitions and better flow. Every piece is TIG welded by our skilled in-house fabricators right here in the USA, ensuring top-notch quality. Plus, we’ve CNC machined the turbocharger V-Band flange from billet stainless steel—no shortcuts here.

Installation? It’s a breeze. Our downpipes are designed to bolt right onto your factory exhaust system or any aftermarket setup you’ve got. You won’t run into compatibility issues, and they come with a brushed finish that adds a nice touch. If you’re into aesthetics, you can also opt for a mirror polish or even a high-temperature black thermal coating to keep those underhood temps down.

One of the best parts about our Competition Series Catless Secondary Downpipes is that they replace just the secondary catalytic converters. This means you can keep your factory primary cats or swap in an aftermarket option without any hassle. It’s all about flexibility and performance.

Here’s what you can expect:

• Higher max horsepower and a more aggressive power curve.
• Quicker torque delivery that hits faster and stays strong longer.
• Improved throttle response and snappier turbo spool-up times.
• Mandrel-bent 3" piping for that smooth exhaust flow.
• 100% stainless steel construction for durability.
• Precision CNC machined and TIG welded for quality you can trust.
• Compatible with factory or aftermarket secondary downpipes.
• All installation hardware included.
• Limited lifetime warranty for peace of mind.

So, if you’re ready to take your BMW M5 to the next level, our Competition Series Catless Secondary Downpipes are a solid choice. They’re track-tested for durability, and you’ll definitely notice the difference in performance. Get ready to feel that power surge!
