We are now carrying the Stainless Works long tube headers for the 8.1.

These headers are manufactured from 304 Stainless, the headers feature 3/8” thick, CNC laser cut flanges, and CNC mandrel bent primary tubes available in 1 3/4", 1 7/8” or 2”. The headers are completely tig welded together, and are designed with a slip joint collector that uses the factory headpipes and catalytic converters for OEM reliability. Stainless Works long tube design makes excellent low end torque and mid range power while maximizing ground clearance. Stainless Works Muscleflow headers are the only ones available with a limited lifetime warranty, so they are guaranteed to last as long as your truck.

They only list these headers for the 2003-'04 model years but they should fit the 2001-'02 trucks also. They just haven't installed these on those years to confirm. I'll be installing a set on my 2002 Silverado HD in the near future.

The part number and price is -

SW81 2003-'04 Stainless Works 8.1 long tube headers $689.99

Orders placed this week should be ready to go in 4-6 weeks. We're offering free shipping for the first 5 sets that are ordered!
