Best Downpipes for 21-23 S58 BMW M3, M4 G80/G82/G83

BMW M Cars are indisputably one of the most legendary sportscar lineups of all time. That’s saying something because there is a lot of stiff competition in the performance car industry. With more and more challengers and competitors with every passing year. In order to stay competitive and remain compliant in ever tightening emissions standards, automakers have turned away from the naturally aspirated engine. Manufacturers have opted into using forced induction to aid their power plants, because It’s easier to make additional horsepower by installing a blower or turbocharger(s). Additionally, turbochargers make it easier for cars to pass ever more strict regulatory standards.

It’s no surprise that BMW and their M car lineup has embraced the turbocharger revolution. Unfortunately, one of the downsides of turbocharging your car is muting your exhaust sound especially so, when your car is an inline six. Car enthusiasts attempt to fix this lack of exhaust sound with cat-back exhausts and it does work, to some extent. However, the largest restrictive bottleneck for performance and sound is your turbocharged car’s downpipes, especially if they have OEM catalytic converters.  In order to get your turbocharged S58 powered G80 M3 or G82/83 M4 to sound its best, you need to replace your OEM downpipes with aftermarket ones. Today we will explore some of the best downpipe options for your G80 M3 or G82/83 M4.

Recommended: VRSF 3″ High Flow Stainless Steel Downpipes

VRSF provides some of the best value of any manufacturer in the BMW aftermarket part community. They produce solid products and have a great reputation amongst enthusiasts. This is our recommended downpipe and by far the most common aftermarket downpipe for the s58 that we see. At the end of the day, a downpipe is just a downpipe. It’s a bent piece of metal piping with some welding done to it. There’s no reason to break the bank with a downpipe, as long as you have proper fitment and optimal diameter any of them will work. VRSF provides a really solid combination of price and quality with their 3” High Flow Stainless Steel Downpipes. VRSF 3″ High Flow Stainless Steel Downpipes (Affiliate link.
