Recently I bought the quad tip GThaus cat-back, does anyone know what diffuser is compatible with it or do I just have to cut the OEM diffuser to fit it?

Thanks for helping!

 

Here is the one that you can use for the quad exhaust tips

 

 

but the toms is for like the diagonal quad tips exhaust right, would this also fit the non diagonal quad tips?

 

Cool! Do you have the same exhaust? The is500 exhaust is diagonal shaped so would it fit these horizontal ones?

 

I believe they will work for either style. They aren’t as offset as the 500’s though when I was looking

 

negative, I had the Takeda AFE one and went back to stock with quad tips, couldn't stand the drone. The Is500 diffuser is both vertically and horizontally bigger, it will fit.

 

Thanks man, do I just go to the closest Lexus dealer and buy an is500 oem diffuser from them? I have the part number as: 52108-53100. Or is there any other place that you can recommend to buy?

 

Check prices online in service parts tab, prices vary from dealership to dealership.
I found best pricing in these two dealerships overall when I look for OEM parts:

Rallye Lexus 340.12$
Prestige Lexus 337.35$

or check lexus parts outlet, they have great prices as well (as a matter of fact, bumper you looking for is the cheapest there):

Lexus Parts Outlet 322.42$

Good Luck!

 

Thanks for the info! I found a drivable dealership with nice price and I can go pick it up so I don’t need to pay shipping.
I called them and they said that they are not sure if it will fit is350. I guess I’ll just buy it and try it out.

Front end is longer on the is500, rear should be the same

 

I'm guessing it is the same as the GTHaus exhaust they used for the "IS 600" back in SEMA 2022 which still uses the factory valence just with the Artisan Spirits rear diffuser.

 

Damn, so you're saying the takeda afe exhaust on your is350 has a lot of drone? I was considering this one because the mufflers still look pretty big, and on the YouTube clips it sounds a bit like the OEM F sport exhaust

 

What brand of bike carrier is that? Looking for something for my IS 350.

 

The drone at 75/80 is horrible, around town it is very nice because you don't sit at that RPM and sounds great. I do 25-50% highway depending on the day of the week so it was a no go for me.
