I am going to buy a used hi power but dont know if they will fit an 06. It is coming off of an 03.

 

Yes, the only diff from what i understand is the added 02 bung on the cat

 

bump would like a couple more opinions

 

yes it will fit, just plug the o2 bung in the mid pipe if you're keeping your stock cat on.

 

It is the same exhaust for both the VIII and IX. The only difference is that the IX has the 02 bung in that cat and you don't need to use the one on the HKS exhaust. You can simply block it off with a bolt. Make sure you get all of the brackets from the person you are buying it from. The HKS exhaust requires relocation of some of the hangers that the OE exhaust uses and if the brackets are missing installation won't make much sense. Click below for reference.
