Smile Quad Diffuser Time!! :)

Howdy all, once again I am asking for your financia- I mean automotive support lmao. Hope everyone's thriving in these crappy times. I have recently decided that its about time to switch over from the stock axleback to a quad tip setup that I've been wanting to run since I got the car, (should have come with quads on the 17+ models idk why they don't). Basically, first I need to get a proper diffuser to fit the quads since the 14-16 models have the boring diffuser that only fits single tips. My question to you guys would be should I try to find an oem 17+ diffuser, or should I focus more on trying to find an aftermarket one? The reason I ask is because they both seem to be around the same price, but the thing with most aftermarket diffusers that I find I need to drill holes to properly mount it and idk how I feel about drilling holes lol. The oem diffuser will fit for sure no problem, but carboon fiberr...... Is the carbon creations IS diffuser worth it, as it would fit quads and look good for only ~$100 more? Any other suggestions for quad diffusers on an IS? just trying to get some good advice. Also if anyone is selling a Tanabe quad tip axleback for the low near IL, you know where to pm me. THANKS FOR THE HELP BOYS!

P.s. if any of you guys have tried the REV9 quad tip axleback let me know your opinions i'm very tempted to pick one up especially for $350 that's like %30 of the cost of any other axleback for my car and I'm a broke college student soo yeah lol

I would go with the F sport 2017+ diffuser, looks really good IMO.. can find it for $100-$150.. those carbon fiber diffusers are like $500+

Installed the Rev9 today. Aligned well with the hangers and came with new hardware. Build quality and welds seem solid but time will tell. I wanted the RC350 Tanabe but its been out of stock for a long time. Only started it up and revved it, sounded great. Waiting on my 17+ diffuser from Lexus, then I'll drive and chime in again.

You'll be very happy with the 2017+ rear diffuser and those quad tips. Here's mine on my 2014.
