Perfect fit for my 1996 Honda Civic LX - 4 door. Engine 1.6L. I installed it with a catalytic converter: ATP 101122 exhaust manifold Very easy assembly. Don't forget to buy gaskets and spring bolts (the old ones are not reusable). Spring bolts: Walker exhaust spring bolt set 35129 If you have any questions, please contact us!
