    Default 03 Longtubes

    I'm thinking about doing long tube headers on my 03 Silverado 1500 with a 5.3, and I was wondering if anyone had any suggestions, including if I should get it tuned after the install. Also I'm curious what I will have to do to get them in place. Any info is welcome.

    I just put in Pacesetter LTs with a 3" offroad Y pipe that bolts it all up to the stock system. It was a pretty cheap route right around $420. I checked out my tune afterwards and it was pretty much right on where it was before I put the headers on, it was running just a bit richer during WOT, but pretty darn close.
