hello everyone i am new here i have a 1990 f250 with a 351 and i was thinking about putting shorty headers on the thing it has all of the smog junk on it i might get by that but what can i do about the egr i need all of the help i can get thanks.

 

The best thing to do is buy headers with the EGR fitting in them, you won't see much of a power boost with shorties on the stock Y-pipe and cats though.

 

well thats what i thought i think i will go with the long tube headers i like them better thank you for the info.

 

Huh? The EGR gets its feed from an exhaust crossover in the intake manifold.

The O2S should be plugged way down somewhere in the y-pipe, so shortys will replace4 the stock irons lickety split (its what I did on my truck using FMS parts)

 

You don't have a 5.8 do you?

 

shorties, bassani y pipe with hi flow cat , your choice in muffler and the 3" maramount tail pipe section that you can get from any autozone for under $40. you can then use either clamps to put this setup together or take to a shop to have welded up.

if you go long tube headers your y pipe will need redone anyway.
