well, i put on edelbrock TES headers, and feel this way.

installation - not to hard, simple hand tools, a lift, and patience made it pretty easy. just expect to have normal headaches associated with working on cars.

performance - AWESOME!!! i was very impressed with how the car ran after i put them on, i could definatly tell the difference.

maintanaince - i got the uncoated ones, so they got "ugly" but im not building a show car, so i dont really care, but the process of burning off the protective coating was a pain in the ass, it was like i had a major valve cover leak. and the main pain in the ass, i have yet to figure out how to get the spark plugs out. the primary pipes go right over the damn things. no room for a socket, and the wrenches dont get in onto the hex heads. so ill have to custom fabricate something to make it work.
