I'm a newbie to this site, so please forgive me if I ask a question and I don't have it in the right posting area. When looking up headers, I noticed it said not for A/C, so I assuming the bracket must be in the way. Is this true? The compressor is off the car now, so should I decide if I want the sound of headers, or A/C ? Also where would I buy a owner's manual, do they make reproductions?
