dude check the exhaust system , i dont think the headers will be the probolem but check the catalytic and the resonator after it and make sure the pipes are good, i buy a 1995 ex and it has a weird buzzing sound ans it was the resonator so i remove it and replace some rusty pipes and the sound was gone. hey how much do you pay for that car????????? i pay for mine 5g (in puerto rico car are expensier) with 173,000mileage on it.. today i reach 175,000 sharp.

 

I only paid 1500.00, which i think is a good deal.
