Hey guys! I've been lurking for a while now, i recently got a 2014 IS350 F Sport 3IS RWD, and it currently has a Invidia Q300 Axle back exhaust.

I'm looking to install the rear valance/diffuser from a 2017/2018 and want to convert the single tip to quad...

would anyone have any good tip brands they could recommend that would work with the Invidia piping?

From what i have gathered on the interwebs, Some say 2.4" some say 2.5" inner diameter, some say 60mm which is 2.36"ish... Could someone tell me what the proper piping diameter is for the muffler tips so i can purchase the muffler tip piping accordingly?

I'm looking to go for something similar to this rear end which i am borrowing from Edwins facelift JDM/EDM build

Anyone know of some tips that would look similar to those? the ones i currently had that are quad on my IS350 are pretty spaced.

The Q300 is a single outlet tip, so i would need to use 2 single to dual (dual to quad) tips converters.

Sorry again about my "lingo" i'm still new to alot of this.

1. Maybe contact Invidia?
2. That's the Apex'i dual system
3. I think it has 3.75" tips

Thanks for the info, I'm hoping to find some tips that can match the Apex'i tips that will fit onto the single outlet on each of the invidia muffler. i really like the sound of the invidia exhaust

first figure out the size of the outlet of your exhaust, usually it's around 2.5"
you're gonna need to cut off your current exhaust tip.
then measure the opening of your rear valance to see what would fit, they are pretty small and not designed for a quad tip fyi.
then find a dual tip on amazon that matches both.

it's gonna look tacky in my opinion since youd have to find small quad tips if you use a quad setup with a rear valance designed for a single tip. i would convert your rear valance to a true quad tip one and go from there.
