I have a pro kit with long tubes and I've bottomed out once over a huge speed bump and that's it.

 

i have a prochamber attached to my stock headers now. what kind of headers u think would match up? bbk shorty's?

 

shorties will match up as stock would. keep in mind that headers are very difficult to change on a 4.6.
everyone said it wasn't that big of a deal but 2 days later, after the start of the install, i had a header leak and had to take it to a professional anyways. good experience but major headache for 8 to 14 rwhp.

 

i heard that long headers take the place of a catalytic is that true and are longs street legal?

 

Not emissions legal in some states.

 

what about in cali

 

Long tubes are illegal in cali.
If you get long tubs get some bbk's from volpaz.com, that is where I bought mine. They were like 460 shipped.

 

are mids or shorts illegal in cali too?

 

anyone have a used set of bbk shortys?

 

Nah, your midpipe takes place of the factory cats. Your factory exhaust manifolds are just well... there.
