Guy's question for you, I'm new to this forum and have a question I hope you can answer. I have a 2016 Lexus IS350 F Sport AWD, it has the factory dual exhaust.


I was looking into the possibility of converting it to a quad exhaust system, besides buying the exhaust system, I thought the only thing else I would need to buy would be the rear diffuser.


But looking at all the pics of the IS 200, 300 and 350 cars it appears that I will have to change out the entire rear bumper in order for my quad tips to fit thru it.


Please advise on what type of bumper or valance I need to purchase along with any other parts I may need.


Also if you can provide me the web addresses, vendor names or how you got your rear bumpers modified I will be most thankful.


Thanks All

I replaced my OEM diffuser with an Aimgain carbon fiber diffuser. If you look on my build thread in my signature below, you can see the details of it. It looks amazing!
