How to Replace the Exhaust Manifold in a Honda Accord

Between 2003 and 2007, the Honda Accord offered a 240 horsepower 3.0L V6 engine with a six-speed manual or automatic transmission. This seventh generation Accord offers straightforward, reliable transportation and is widely popular among used-vehicle shoppers. Removing and installing the exhaust manifold is rather straightforward, too.
