Aiight got a 94 Ferio stock size piping,catalytic converter & resonator but a flowmaster muffler.
Got a new muffler with a 4" angel cut tip.
Thinking of running 2.0" piping and doing away with resonator but keeping cat..
Or maybe do away with cat all together?
I'm pretty sure I want bigger piping I forgot the diameter of factory exhaust
but i measured it and it was like 1 5/8

 

oh and BTW just so i dont get flamed.
Loud isnt a problem.. I live in the middle of nowhere
Call it Hickville U.S.A Low N Loud thats how I <3 em.

 

If you are not concerned about noise, just run it from the header off

But on a serious note:

You can weld anything together, but it may not run as good as if you were to get something custom fit for your car... Most shops will make you an exhaust for a good price, and weld any muffler of your liking onto it

 

Is 2.0 piping alright i mean its just a d16z6 im not tryna go for 2 1/4 bc ground clearance is an issue...
