I searched and couldn't find info. If putting a IX bumper on an VIII and upgrading the FMIC at the same time, which generation core should I buy? ETS comes in 22 ad 24", for the IX and VIII respectively. Is that correct the IX FMIC is narrower and that's the only difference?

 

I am very happy with the way my 24" wide garrett cored ets fits in my 9 grill opening. If you go with any garrett core the majority of them are 24" (standard tank)

 

That's good to know, thanks. So now I just need to know if the ETS IX FMIC will fit the VIII chassis?

 

It should man. I have the ETS 3.5" Widetank on my 03 and everything fits like a glove

ETS FTW
