3" Aluminized Turbo Direct Pipe - 04-10 Duramax 6.6L 321056

When upgrading your exhaust system, don't overlook the turbo direct pipe. The factory turbo direct pipe is "flattened" and can be fairly restrictive to your exhaust flow, so you won't see the full potential of your exhaust flow improvements until you upgrade that as well. Our Diamond Eye Turbo Direct Pipe features CNC machined end forms for a precise fit, mandrel bent tubing for smoother flow from the turbo and is covered with a special thermal-resistant wrapping to help reduce EGT's by up to 150 degrees. Incorporate this with one of the "Quiet Tone" exhaust systems for maximum exhaust flow and performance.

Replacement of the Turbo Direct Pipe is a fairly difficult job. Be prepared to spend some time due to limited work space.
