AHH.... the age old question of what is better?? CAI or SRI. lets not bring that up again. Lets just keep it at, ITS ALL PERSONAL PREFERENCE.
I dont have any pictures of my header installed, simply because I had it done within a 2 week period over christmas break and I dont have my car with me while I am away at school.
The header cost me about $280 from protephile, who is an awesome vendor. I had it ceramic coated, "gray ice", which is a metallic gray cast iron sort of color [simply beautiful], for $160. The guy at the coating shop offered to help me install the header for free. Its simple enough to install on your own if you have the tools, otherwise, you could overpay any shop to do it for you for a small (killit)ass raping fee of anywhere between $50 - $80.
I would definetly recommend getting it coated because it is worth every penny. Overall your budget should be between $250 and $500 depending on what you want to do, and what brand of parts you want to go with.
