If you’re looking to boost your BMW M5 or M8’s performance without sacrificing emissions compliance, the PLM Catted Downpipes are where it’s at. I’ve had the chance to install these on my own F90, and let me tell you, they make a noticeable difference. These downpipes are designed specifically for the M5 and M8, so you know they fit right in without any hassle.
What really stands out is the craftsmanship. Made in the USA, these downpipes are built from 304 grade brushed stainless steel, which not only looks good but is also durable enough to handle the heat. The mandrel bent 3" piping helps improve exhaust flow, and that’s key for reducing backpressure. You’ll feel the extra power when you hit the gas, and it’s a thrill every time.
One of the best parts? They come with high flow catalytic converters, so you can enjoy the performance gains while still staying within emissions regulations. It’s a win-win. Plus, they retain the factory mounting brackets, so you won’t be struggling to get everything lined up. The high-quality flex bellow joints and CNC machined V-band flanges ensure a solid fit, and they even include O2 sensor bung holes, clamps, and hardware for an easy installation.
These downpipes cover both the primary and secondary sections, which means you’re getting a complete upgrade. And if you’re worried about longevity, they come with a one-year warranty, which adds a little peace of mind.
In terms of fitment, these are perfect for the BMW F90 M5 from 2018 onward and the F92 M8 from 2020 onward, specifically for the S63M and S63R engines. If you’re serious about enhancing your ride's performance, these PLM catted downpipes are definitely worth considering.
