Manifold is well made but will not fit 1999 Nissan Frontier 2WD 5 Speed Transmission. It says it's for 2WD and 5 speed, but the pipe is about 8 inches from where it connects to the catalytic converter. Also, one of the sensors isn't up to standard so I'm not sure if they sent me the wrong one or what, but it was completely disconnected from the pipeline. The seller refunded my money straight away so that was a plus.
