well was looking to buy some 2" kooks fbody headers, i know you can make them fit in truck but what all does it have to be done.?? thanks in advance, if yal have pics that will be even better

 

I just tried some kooks 1 7/8 super competition LT's off of 02 T.A. Paseenger side went on perfect but driverside wouldnt fit, i even tried beating it in just a little to clear but it still rubbed, and wouldnt clear the engine crossmember..

 

pm txsilverado. he had some stepped 2" to 1 7/8" with 3.5" collectors. pretty sure he didnt do anything to make them fit

 

Dunno if this helps at all but Banker099 has or had a set of TSP f body headers on his, I believe they were 1 7/8. Maybe see if they sell a 2" set.

 

I have the tsp 1 7/8 headers on my 01 and the fit fine just got bend the Tranny lines so there out of the way

 

2" F body kooks here. Driver side fit fine, passenger side hit the frame to the point it had to be notched. Also, had to cut the ears off the trans on both side. nothing to it.

 

I have 1-7/8" to 2" Kooks f-body headers and my #6 primary tube barely touches the pass side frame which you can see in the following pic. You will also have to get creative with the y-pipe.

 

what the hell kind of motor are you planning to need 2" headers for? i think you'll be fine with 1 7/8 headers. 1 7/8 stepped to 2" max. 1 7/8 will fit better due to the 3" collector. my stepped headers with a 3.5" collector was extremely close to the frame because it was 3.5 and i reduced it to 3" anyways.

 

im also trying the tsp f body 1 7/8 myself but knowing roman he has something up his sleeve to push some hp out the 2 in headers but each to his own

 

Guys since I am going to be running a procharger I am trying to keep the exhaust flow as much as I can so I can make as much power with less PSI ... so 2" hit the frame??
