Speed Engineering Silverado & Sierra longtube headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our Silverado & Sierra longtube headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our Silverado & Sierra longtube headers have been dyno proven. We stand behind our Silverado & Sierra longtube headers in saying you will not find a better fitting, quality built, budget header for your vehicle.
Features include:
Vehicle Applications:
Revised Y-Pipe: Now works with 4L60E & 4L80E transmissions. Also allows more room for 4wd vehicles.
Note: If using a larger 4L80E transmission the bellhousing ears may need to be trimmed for proper clearance.
Note: Earlier 2500's might have fitment issues due to chassis being designed from previous years.
Note: Most 6.0 applications have a 2 into 1 exhaust system which our y pipe system will not work with. Double check your exhaust for confirmation of fitment with single exhaust. Our x pipe kit can work on the 2 into 1 exhaust systems, but require fabrication for connection.

Yes I received them and they are in good shape just as expected
Drivers side is real good but the passenger side sucks personally I would have ran the runners a lil bit more forward as there is plenty of room to do it because 2 and 6 plug wires don’t fit without getting toasted and number two plug literally have to unbolt the header to get the wire and plugin and out and that’s after massaging the runner
Good fitment on 2005 crew cab.
I don't know if I recieved a set with design flaws but the passenger side header is too tight on cylinders 2, 6, and 8. I can barely get the plugs installed and they keep burning plug wired and I've tried 3 different styles. With all the room on the passenger side of a 6.0 in a truck the primaries bend to close to the head causing these issues. It looks like they could have clearances the headers a little better to keep this from happening.
Sounds damn good for the price and they get the job done just fine
