ok im just seeing if i have everything i need, i have long tube headers with matching y-pipe, i have header reducers, have the gaskets and bolts, and im getting o2 sensor extensions, will i need anything else ?

are these the right o2 sensor extensions ?

 

Looks like you're good to go. Make sure you have a 3/8ths 12 point socket to get the header bolts right. The O2 extensions are the correct connector. My only question, why do you have 2 reducers. If you have a Y pipe that is made to go with your headers, it's inlet should be the same as the header collector. Then it Y's together, so to get back to the stock exhaust size you should only need 1 reducer, or if you're running a 3in. cat back you shouldn't need anything.

 

i just thought i would need 2 reducers, oh well i will just keep it in case i guess, will i need any new hangers or anything ?

 

you shouldn't need hangers
