Well, I got my headers on over the weekend and am pretty happy with the results.

Dynatech redesigned the driver side header so none of the primaries loop over the top and cause plug wire interference anymore. The new design give plenty of room for wires.

I had dynatechs on my old truck with the 5.3L and they were decent but, they really are noticeable on the 6.0L. WOW! There is a definate SOTP gain in low/mid range torque which is nice when just cruising along on the highway. It seems my mileage might be a little better but, I'll have to wait for a couple more full tanks to judge that. At WOT not only does the truck sounds a ton better but, it seems to have picked up very nicely.

I'll be going back to the track in September so I'll be able to judge how much they picked up. The only other mod I'll have is a cut out air box so it'll actually be results from both things in one.

I woulda got pics but, one of the O2 sensors got me too irritated trying to take it out and I didn't get the pics.

There was only one snag. It seems my truck and maybe some others(not sure what years/models) have a different style front O2 sensor and the extension they sent was the wrong one for my O2 sensor. A quick call to Dynatech and they were more than happy to take care of the situation.

Maybe I'll get some pics later, gotta go.

 

Congrads! Maybe some day i'll get some of those

 

good work. Did you have a car lift or fought it from the ground? How long did the install take?

 

Congrats!
A computer tune will take advantage of your new mods.
My mileage went up about 1+ MPG. The new sound is an added bonus.
ENJOY!

 

bout time you did somethin to the truck
Good choice on the LTs!

 

That's cool, congrats.

How was the physical install of the headers themselves? Did you have to remove the steering shaft or dipstick tube? Which way did they go in, from the top, or underneath?

I'm itching to do this myself, the last header install I did was on my '94 Z28, and all the extra space on my truck practically begs to be filled with a set of headers. Shoot, you can even see all of the bolts holding the manifolds in and dont have to hire a midget contortionist to get the spark plugs out.

 

I too have the new redesigned Dynatech LT's. Just got them back last week from Nitro Plate. The finish of their ceramic coating is very nice. It has a great polished aluminum look to them. They coat the inside tubing as well.
Can't wait for the install of them along with the other numerous boxes of goodies just laying around.......

congrates, now post some pics lol

 

I will in due time. Just don't feel like pulling the goods out of their boxes quite just yet.
