Does anyone know what sort of job changing headers on a 2001 mustang gt involves? big job? pain in the ***? expensive? I currently have stock manifold with MAC Pro chamber (no cats) and Magnaflow at the rear.

Thanks,

 

Are you looking at shorty or long tubes?

 

Both are a PITA, but for L/T's you best bet is drop the K member

 

I did my L/T's w/o dropping my k-member.



Would I do it that way again NO!
