Alright I'm thinking of getting my g/f headers for her birthday and a few other mods thats coming up soon. A friend of her's has the Mac Long Tubes and she likes them so I am leaning towards those for her. What else do I need to complete the header job? O2 extension, 3" gaskets or 2.5 gaskets?
Only other exhaust mod she has done so far is the Mac prochamber h-pipe

Thanks in advance

 

your going to need a shorty mid pipe

 

Stock gaskets/ bolts are fine. Only thing you'll need are 02 extensions and possibly MIL's.
