Re: Help-01 Civic HX parts

It will fit, but you need to modify your exhaust. HX has built in catalytic converter attached to the exhaust manifold, and another converter attached at the end of the down tube. EX has only one at the end of the down tube. So if you want to use exhaust manifold for EX, the you either have to go get new exhaust manifold and catalytic coverter assembly for EX, or have a muffler shop modify existing to custom fit. Also HX has 3 oxygen sensors instead of 2 for EX. So you would have to create a bung on the exhaust piping and set the sensor.

And here are my 2 cents. HX is not designed for power, rather it is designed for efficiency. If I were you, I would leave the exhaust manifold alone. Just spend a couple of hundred on nice CAI and it will be better than replacing the exhaust manifold assembly for $1000 or so...
