I did not have the kahunas to cut and weld to make it fit an NA. It tapers to a 2.5" at the end. It has 2 piece design, with two o2 plugs, one in the "Stock" location and another further down for your wideband. The flange that connects to the cat has been cutoff. Asking 170 shipped or 150 picked up in San Diego.

 

No one wants it? Come on! Sell your NA and buy a NB!
