im pretty sure im going with those, but Randy at thorley said I can only use the shortie's? number 309?

These are for a 04 4x4 and he said they would be good for 10-13hp from the dyno's they have done.

I wanted their long tubes so this kinda puts me in a jam now?

any info on this?

 

I thought somebody was running them on a 4wd????

 

Even there website says 4wd.http://www.thorleyheaders.com/gm_headers.html

 

I got a set on a 2000 4x4.The fitment is great.I just love the sound.

 

i dunno why the guy from their site was telling me I could only run shorties?

those with them for the 4x4's, what part number did you order and from where?

 

could you post some pics, Im wondering how long they are in comparison to other lt's

 

id like to see some photos installed also

 

I'd like to see them too. Went looking at Summit's site and couldn't find any LT's from anyone for our trucks there.

I guess those are the ones that will fit 04's also? Just need block off plates for the air and crap right?

also, what y pipe comes with those headers? Offroad or catted? This will bolt right into the stock pipe also correct?

 

I called them and they told me the 310 y would work on newer model 4x4 just have to block off the egr fitting
