Product Details

The MBRP GMCA424 is a high-performance 3-inch turbocharger downpipe designed specifically for 2004.5-2010 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This downpipe is CARB compliant (EO #D-763-2), making it legal for use in all 50 states including California.

Constructed from heavy-gauge aluminized steel with smooth mandrel-bent tubing, this downpipe eliminates restrictive bends and increases exhaust flow from the turbocharger. The mandrel bending process prevents rippling in the pipe walls, ensuring maximum flow efficiency for improved turbo spool, reduced exhaust gas temperatures, and enhanced engine performance.

Key Features:

  • 3-inch diameter mandrel-bent aluminized steel construction
  • CARB compliant with Executive Order #D-763-2 for 50-state legality
  • Direct bolt-on installation with no modifications required
  • Reduces backpressure and improves turbocharger efficiency
  • Enhanced exhaust note with deeper, more aggressive tone
  • Fits mid to late 2004 through 2010 model year trucks

This downpipe provides a significant upgrade over the factory restrictive unit, allowing your Duramax engine to breathe better and perform more efficiently. The improved exhaust flow contributes to better throttle response, increased horsepower and torque, and improved fuel economy under load.

Hey can't beat free shipping. We will see how long it takes to receive though. Takes about a week in a half. Be sure to check your package, I opened mine up a week after I received it and notice one of the seats have a tear in it. So hopefully they can take care to that for me sense I waited so long.

Looks like best price found on new item. When received, exactly as described and fit perfectly.

SO FAR SO GOOD

Good so far

Nice!

I have been looking for rain guards for my car for 6 months now I finally found hem fast and easy check out :)

Ordering is easy waiting on shipment to check accurate item??

VERY QUICK AND EASY! BEST PRICE ONLINE, PERIOD!

efficient, like shipping discount in return for email promo, definitely like follow-up

So far so good, best price I could find that actually had the part in stock

it was quick and convenent

I found it fairly quickly and without much hassle, however i was unsure if it was the part i needed because of lack of details.

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.
