OEM and cheap
You literally cannot find OE injectors cheaper than this, not to mention they arrived at my house in 2 days, highly recommended.

Great long tube headers highly recommended
I purchased the long tube headers for an 04 GMC Sierra Crew Cab 2 wheel drive with a 5.3 The headers fit great, it was a lot easier installation than I expected it to be. There were no modifications that had to be done to fit them to the truck nor did I have to bend or dent any of the primaries. The installation took about 3 hours with myself and a friend using jacks and jack stands in the driveway. I highly recommend buying factory style manifold gaskets and locking header bolts to keep from having any problems further down the road. As far as performance and sound goes the truck sounds absolutely amazing I could not be happier with the way it sounds now. Performance-wise I'd say I lost a little bit of bottom end not enough to make me regret buying them or not buy them for my next vehicle but you can tell a tiny bit. On the other hand top end is where the headers really shine the truck pulls like a freight train when I'm passing someone on the highway. My MPG surprisingly got significantly better I'm averaging another 4.8 MPG on the highway and 2.3 MPG in the city.
