Product Details

The MBRP GMCA428 is a 3-inch turbo downpipe designed specifically for 2015-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L Duramax diesel engine. This high-performance downpipe maximizes exhaust flow between your turbocharger and exhaust system, reducing backpressure and improving engine efficiency.

Key Features:

  • Mandrel-bent 3-inch aluminized steel construction for smooth, unrestricted exhaust flow
  • Black powder-coated finish for aggressive styling and corrosion resistance
  • Bolt-on installation with no cutting or welding required
  • Designed for 3-bolt flange turbo connection
  • CARB EO# D-763-2 certified for legal use in all 50 states including California
  • Enhanced exhaust flow reduces turbo lag and improves throttle response

Manufactured from heavy-gauge aluminized steel and featuring mandrel-bent tubing throughout, this downpipe eliminates restrictive bends and maintains consistent diameter for maximum flow. The durable black powder coating provides a sleek appearance while protecting against the elements. MBRP backs this downpipe with their industry-leading warranty for long-term reliability.

Important Note: This downpipe is compatible only with turbochargers using a 3-bolt flange connection style.

well designed site

very good response with order but it was the wrong part that i was needing. I will be returning both temp switches this week along with the temp sensor to see if you can match up the size and thread pattern that will fit inside the block where the temp sensor was previously located. Thank You.

Thanks
