If they don't, do I need to buy them?

 

No, they do not come with extensions. They have the bungs welded before the collector, but you need to buy extensions.

 

Do you know how long i need to get them?

 

TTT
What length 02 extensions do i need to get?

 

I have a 94 and mine are about 2 feet long, worked out great for me.
Better to get them too long than too short, it gives you more leeway on routing them.

 

i did not need the extension on my driver side, but passenger DEFINETLY. the LTs do not come with them, but you can order them at the same time you order the headers.

Jet-Hot = Great customer service

 

I purchased the 02 extensions from Jet-Hot when I bought a set of Jet-Hot LTs. I think the extensions were $25 or so. The other option is to buy some wire and extend them yourself. I've seen people solder pieces of wire to extend them and others have just used wire & crimp connectors. If it were me, I'd just buy the extensions and be done with it.
