I saw that one too. He did have to get the hammer out to make a tad bit of clearance for the balance weight on the front driveshaft not to hit. I can't figure out why they can't design headers to give us 1/2 inch of clearance from the driveshaft.

 

I agree, my SW's clear the driveshaft by a mile, but they're real tight on the passenger's side frame, and it seems like there's enough room over there that there's no need for them to be that close. Doesn't make sense?

 

My crappy OBX's hit the driveshaft and were rattling on the passenger side frame...
That's what I get for trying to be cheap...

 

I don't think the Dynatech's were ever designed for 4x4's.

 

well i contacted llp and told them i put them on my 2007 silverado classic and there reply was i think i know which model truck i have lol

when i first put these on nothin hit anywhere,it was only after i had the truck offroad that i saw the damage.Soooo whats the point of the headers if i cant use them in all condtions??

 

Good question. The way I see it there is enough room to build in plenty of clearance and for some reason they are failing to do it. Hope you can get something worked out.

 

DAmn sucks to here, hope you get things right.. I know where you can get some Stainless works headers at....

 

I've got dynatechs on my 02 4x4 and they fit perfectly with plenty of room on both sides! The only thing is that there expensive as hell! But they were worth It with thick flanges stainless, and will never have a gasket issue!

 

could be how your pipes, muffler etc are set up... im guessing if theyre moving around and such i could see thats why your having problems...

ive launched mine a few times in 4hi with no problems, and i even did some minor hill climbing today with no issues... maybe your set might of been a odd ball set?

could be a number of things... i know i was expecting mine to have all kinda problems just with my luck but hate to say it... nothing yet...

 

have you had your truck flexed out tho?i had mine on 3 wheels a few timeswhich could have caused it,but still ya know...
