just so you know its not going to be cake to install it unless you get lucky. i ran into many problems on my o/r x specially unbolting the stockmidpipe where they are connected to the headers, and also plugging the front o2 sensors back in when you get the prochamber on. but i am 17 and didnt really know what i was doing too much but i had to make many trips to advance to get the right tools and bolts so that didnt help any.and im pretty sure on the 04 you need o2 extensions.
anybody know what tools, extensions i will need to install the catless mac prochamber on my 02? ive also heard not use the gaskets included with the mac.
