The Diamond Eye 341007 5-inch aluminized steel 2nd section tail pipe completes high-flow exhaust systems on 2001–early 2007 Chevrolet Silverado/GMC Sierra 2500HD/3500HD trucks with the 6.6L Duramax diesel, providing a straight-through extension from the muffler to the tip that reduces backpressure for faster turbo spool, dyno-proven gains of 10–15 HP and 15–25 lb-ft of torque, and improved fuel efficiency during heavy towing up to 18,000 lbs.
Constructed from heavy-duty 16-gauge aluminized steel with mandrel bends and a perforated core, this tail pipe delivers aggressive diesel sound without drone while resisting corrosion and heat up to 1,200°F.
