I'm upgrading the exhaust system and i'm trying to decide on what stlye of header i should go with shorty style or long and what brand i should go with. i already own the ss cat back exhaust. any input would be greatly appreciated.

welcome - which exhaust do you have (what diameter) and what are you doing about the cat?

i have a catback exhaust system ss 4.5" tip 2.25" light weight piping n1 style titanium tip chances are i'm gonna need to change the catalytic converter.

With a long tube header (eg: the OE SVT one) you will definitely need a different cat and you will have to modify your cat-back exhaust.

OTH, most of the shorty headers IIRC work with the stock Zetec cat which means you can keep your current exhaust intact.

what kind of modifications to the catback exhaust would i be looking at do you know ?
