Does anyone know the collector size on the D16 4-2-1 X-Force Header please
Will this cat bolt onto it?

Or would I be better off getting a 2" Magnaflow Hi Flow Cat...
My exhaust is 2".

On the X-Force site,I'm sure it says a 60mm collector.Which is 2.25".
So is it worth upgrading to a 2.25" exhaust and a 2.25" Hi Flow Cat?
My car is an Automatic 96 EK Civic Sedan.I'm not sure what to do,cause I know Honda's like back pressure and being an Auto...

If I don't do the above I will leave the 2" exhaust and get a 2" Hi Flow Cat.
Help plz

I think 2.25" is too big for 1.6l non-vtec engine.

Back pressure... some people say they are good but mostly say they are not good for performance. How do you know it's good?

Thanks Twing.
By back pressure I mean a 2" exhaust will be better than a 2.25".Just to make it clear...
But yeh I was told by a couple of exhaust places that Honda's like backpressure.
