Ready to take your turbocharged Mercedes to the next level? Our M178 Race Downpipes are the perfect way to unlock more power and enhance your driving experience. By reducing backpressure, these downpipes help your turbos spool faster and more efficiently, which means more boost and better performance. Plus, with a tune, you'll see a noticeable increase in power, and enjoy a more aggressive exhaust note that’ll make your AMG sound as good as it drives.

Made from durable 304-grade stainless steel, our downpipes are built to last and designed for maximum flow with smooth transitions. This means less restriction and more power where you need it. And don’t worry, they come with SPOOL’s lifetime warranty, so you’re covered for the long haul.

  • 304 Grade Stainless Steel for strength and corrosion resistance
  • Optimized Flow Design that improves turbo efficiency
  • Significant Power Gains with a tune
  • A Deeper, Aggressive Sound that matches the performance
  • Lifetime Warranty for peace of mind

Perfect fit for my RAM

Installed both filters on my 2011 RAM 3500 6.7L Cummins and everything fit properly. Nice having both filters in one kit instead of ordering separately.

Convenient and worth it

This kit made the service much easier. Both the oil and fuel filter came together, which saved me from searching for each part individually.
