So I'm taking my IS350 for all the current recalls but was wondering will the dealer say anything about my hks hi-power exhaust. any suggestions should I play it safe and put my stock exhaust back on.

 

Nothing. It has nothing to do with the recalls, or anything else for that matter.

Unless you complain to them that the bumper melted from the exhaust, or the car is too loud, etc, etc. there's nothing they have to say about it.
