Magnaflow 3" Turbo Outlet Down-Pipe For 2004.5-2007 LLY/LBZ Chev/GMC Duramax 6.6 500HD/3500; Extended-Crew Cab/Short-Long Bed
Duramax exhaust systems, no matter the manufacturer, do not go all the way to the turbo. There is a short, flattened cast iron down pipe that remains on the truck when you replace your exhaust system. This cast down pipe is highly restrictive and although is difficult to remove is well worth the effort. Improve throttle response and turbo spool with this upgraded Magnaflow 3" Down-Pipe.
Stainless Steel and High Temp Coating with Fiberglass Wrap.
