I am looking at getting a set of longtube headers for my 99 ecsb with a 5.3 and was wondering if I will need to add some length to the O2 sensors wires. Also how difficult are they to install. I was looking at the hooker 1 5/8" primary tubes any thoughts would be greatly appriciated.

1/4: 15.66@88.1 Before Nelson, headers, and de-cating
Also 69 camaro SS 350 4speed, 13.81@103.6, Ls1 swap planned
i know this is a dumb question. but whats the difference between long tube headers and shorties?

THe long and the short of it is the length of the pipe before the exhaust gases are merged. Shorties have short primary tubes and merge close to the head. Long tubes merge the gases much further away, about midway back the length of the transmission. Long tubes are always better for performance.

is your truck 4x4 or 2wd? If its 4x4 you will need ASM, togs, SSworks, or thorleys
pacesetter LT's only fit 2wd setups and they are around 300bucks
but you shouldnt need any extensions.. mine didnt with the ASM's
