Hey guys, I have an 04 GT with and I just bought a Pro-Chamber to go with my MAC cat-back. I've been reading through some of the threads and I'm not sure what all I'll need. Do I have to have the MIL eliminators? I've also seen where someone said something about need extensions? What are the o2 extensions and do I need them too? Thanks for you help.
