EG3 exhaust diameter

[hayashi_1986]

Does anyone know the diameter of the exhaust that comes off of a EG3 breeze? The cars undergone a full EFi engine conversion to a D16Y1 and has kept the stock exhaust off of the EG3..and I'm assuming its restrictive as shit at the moment. Any info on this would be great! :D

Thanks!

not 100% on this
but all EG exhast pipings are same size.
except for the SIR

either way, si/vti is like 1.75 press bent junk so just go aftermarket off the shelf, or even custom. id say something like 2inch mandrel bend

I've got a 5zigen 2.25inch exhaust system coming in next week, same goes for the headers (DC Sports). I'm assuming it'd make a fat difference in performance after its thrown in. Right now its still running on EG3 piping with VTi running gear :o Any ideas on a catalyst? I heard the VL cat's are good to use :D
