1997 civic ex d16y8 85516 miles. Just recently I took an aftermarket racing muffler off the civic the new muffler is a bosal stock aftermarket. The exhaust system still sounds loud like the racing mufflller.
I contacted the company the muffler came fom they said it meets stock specs and should be quiet.
Also the car idles around 100 and 200 rpm when warmed up the air conditioner has to be turned on when stopped at red lights so the rpm goes to normal if not the car sounds really loud and accelerates slow. Ther are some external modifications on the car like lighter underdrive pulleys, cool air intake I wonder if the cool air intake is causing this problem.
Does anybody have an idea of whats going on?
have the same problem?
