they are for an F body. the 1 3/4 stepped to 1 7/8 clears the frame by a mile. the bigger ones that i got need a little tweaking to get them off of the frame.

 

had to move some transmission lines away from the starter and then they slid right in. they did need some tweaking. we stuffed a 2x4 between the frame and collector before welding up the exhaust. once everything was welded in we took out the 2x4 and it now clears the frame by about a 1/4 inch.

 

i got better....a video

 

those are codys headers now. 1slow01z71. he stole them from me

 

let's see the video lol

 

you'll have gains no doubt, your biggest improvementwas ditching that lowsey Y pipe, any Y pipe for that matter is worthless you ask me well for anyone putting down some decent horse power , you did what you needed along time ago and that was to get the stepped headers.. glad you got them working for ya, good luck on the outcome and new times you'll deffinately have some gains and times worth dicussing on the forums


have a told ya lately i am building my ecsb back since it has a 6.0 i might as well do something with it right? lol j/k bro

 

Those are the prettiest long tube headers I think I've ever seen

 

prettiness that performs lol!!

 

i wish you would put the ecsb back together. or give me the 6.0 out of it lol.
