If you’re looking to squeeze every last drop of power out of your 2025+ BMW M5, you’ve got to check out the Competition Series Catless Downpipes. I’ve been around the block with exhaust systems, and let me tell you, the factory setup is a real bottleneck, especially with turbocharged engines. Those stock catalytic converters? They’re like a traffic jam for your exhaust flow. With their honeycomb structure, they might look fancy, but they create a ton of turbulence and slow things down. That’s where this catless downpipe comes in—it’s all about freeing up the exhaust flow and letting your engine breathe.Replacing the factory downpipe and catalytic converters with this setup really makes a difference. You’ll notice an immediate boost in horsepower and torque. The way it’s designed, with mandrel-bent 3-inch piping, ensures a smooth transition to the exhaust system. Plus, it’s made from 100% stainless steel and TIG welded, so you know it’s built to last. Whether you’re hitting the track or just cruising around town, better throttle response and quicker turbo spool times are just a few benefits you’ll enjoy.Now, let’s break down some of the specs. The Competition Series Catless Downpipes replace both primary and secondary catalytic converters, so you’re getting a full upgrade. This setup not only enhances your power curve but also improves initial torque. You’ll feel that torque hit faster and stay strong longer, which is exactly what you want when you’re pushing your M5 to the limits.And if you’re worried about underhood temperatures, you can opt for the high-temperature black thermal coating. It’s a nice touch that helps keep things cool. Installation is straightforward too—everything you need comes in the kit, and it’s compatible with both factory and aftermarket exhaust systems. Plus, it retains the factory slip-on style connection, making it a hassle-free upgrade.In terms of durability, these downpipes have been track-tested, so you know they can handle the heat. And of course, they come with a limited lifetime warranty, giving you peace of mind.So if you’re ready to unleash the full potential of your BMW M5 G90 with the S28 engine, the Evolution Racewerks Polish Finish Catless Downpipes are definitely worth considering. Trust me, once you feel that power difference, you won’t look back.
