I am not asking whats good/bad but...

I have a 99 dx hatch with a b16a in it.

If I buy an Apexi N1 catback, do I buy it for an si or 99-00 hatchback?

Will this direct bolt on? Do I need to do anything special to get this up and running?

Can I buy a 99-00 si cat converter and dc header?

I just basically need someone to help me piece this together from the engine back.

I believe the piping is the same diamiter dispite the motor, with that said you should buy it for the Hatchback. But I would imagine since your on a B motor and no longer a D, you will have to modify or fab a piece to mount it.

I would email or call Apex and ask them if they offer there N1 for the hatchback w/ B motor. Its a very common swap so I would imagine they offer it or could tell you speficially whats needed.
