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

there is no true "quad exhaust system". if you want the look, all you need to do is change out the tips. you may need to shave/cut a little of your diffuser to make it fit

Hi dnaians:


Thank you for your comments concerning quad diffusers, now I know what I need to do if I go the route of a quad diffuser.

TRD makes a diffuser that will easily fit a quad exhaust set up how ever you can easily just shave part of the diffuser off and the replace later on if you choose to do so

You can purchase the Tom's rear diffuser and exhaust that come with 4 quad tips and a diffuser. I have a customer picking one up, and I'll post some pictures of them when it arrives!
