2003 Lightning Headers. Long vs Short?
<HR style="COLOR: #d1d1e1; BACKGROUND-COLOR: #d1d1e1" SIZE=1 itxtvisited="1"> <!-- / icon and title --><!-- message -->
Hello gang,
I have an 03 Lightning with a magnaflow muffler withstock exhaust manifold and cat. I am considering installing headers and a high flow cat. I will retain my magnaflow muffler but am trying to find out if anyone has done this for their Lightning and if there were any issues with installation/ lost back pressure/ or burning out starters.
I was thinkning that shorty headers would reduce lost back presuure more so than the long but am not sure. I definatley want a more aggressive sound and better performance. Can anyone help or lend some advice or recommend a header?
Aslo, I noticed that the 03 lighthning has two cats per exhaust bank and the header kits I found only have one cat per side. Does anyone know how many O2 sensors there are on the 03 Lightning? Just want to make sure that if there are actually 4 O2 sensors that two wont be hanging and mess up the emissions. If there are only two O2 sensors then I don't see an issue otherwise.
Please help,
Thanks!

Well I know nothing about the lightnings so i totally understand if you disregard what i say. From what little I know about exhaust systems the long tubes are always better, and backpressure is not an issue really. Sorry I couldnt help with the details but if nothing else i bumped the thread back to the top. lol

Longtubes all the way. All the kits that I know of only come with to hi-flow cats. There are 4 o2 sensors on the Lightning and the mid pipe will come with bungs for all of them. Now, is you truck stock? Headers in any form will not net you any gains on these trucks if you are. It will sound better but thats alot of coin for a little sound.
