Would the ed cat back exhaust fit the ef i6?
I have a chance to buy one with little use.
Cheers Chas.

Should do. You can always go to a website of an exhaust manufacturer such as Lukey and look at there catalogue and see if the same part number is listed for both...
I assume both vehicles are the same body type? I.e. both SWB sedans or both wagons. As the tailpipes differ depending on body shape.

Yes it should. My exhaust is a Lukey, listed for EA to AU non IRS sedans.

Thank you twr7cx and krisisdog for the info.
