Re: WHAT?! DT Big Tube Swap headers???
 

I've waiting on a set of these. Hopefully they will be worth it! Any idea of how I could get a few measurements of the dimensions? Really just wanting to confirm they will hang no lower than the bottom of the frame rails. I have an LS3 mounted to a Porter Built Xmember, so if I am correct that should raise to motor 1 or 2 inches from original placement. Any input is greatly appreciated.

Looks like you are selling DT with 1-3/4" primary. I am after the "BIG" DT with 1-7/8". No offense, but if your looking for a quick sale you should be a bit more detailed with inquires. Thank though, and let me know if you stock the DT THY-323Y-C.

Re: WHAT?! DT Big Tube Swap headers???
 

These are the 323s, I have had communication with DT and in initial discussion they said they were 1 7/8" and later communication, ie they are boxed up and on their way to me it says they are 1 3/4".
I will see if I can get in touch with someone to confirm, if not, then I will measure them when they arrive. they are intransit from DT/California to SC.

Re: WHAT?! DT Big Tube Swap headers???
 

they are 1 7/8" headers...just as many asked for!!

Re: WHAT?! DT Big Tube Swap headers???
 

Alright, now were takin... :metal:

Re: WHAT?! DT Big Tube Swap headers???
 

Now they can concentrate on 73-87 headers??? Maybe just skip the small tube and go right for the big ones?

Re: WHAT?! DT Big Tube Swap headers???
 

U will have to discuss this with DT and have someone leave their vehicle with them.

Re: WHAT?! DT Big Tube Swap headers???
 

Herron Performance has them all. The GP in the vendor section is extended thru September. Once these are gone I am not sure how long it will be before they will be available again....

Re: WHAT?! DT Big Tube Swap headers???
 

Would like to make the change to these (and sell my Dynatech's) so my trucks ready to go lower in the future via a new IFS...just have to save the coin!

Re: WHAT?! DT Big Tube Swap headers???

Re: WHAT?! DT Big Tube Swap headers???

Re: WHAT?! DT Big Tube Swap headers???

Backyard, did you buy a set yet?

Re: WHAT?! DT Big Tube Swap headers???
 

I'm afraid to drop the coin on a set and find out they won't work with my DM. If no one posts some installed pics I may pull the trigger on a set after the first of the year and see what happens.
