I'd keep the integrated Genuine Lexus tips! Looks high end factory expensive and professional! I wonder if they bolt on

You'd be able to tell by holding the new exhaust up to the car (on a lift of course) or put your stock vs. the new on top of each other

I'd be interested, but I have the stock diffuser right now...so even if it was a direct fit, I couldn't use it yet. Maybe someone with a quad tip diffuser will step up before I get around to it???

Heard back from Tanabe. Exchanged a couple emails. Seems they haven't tried it, so can't confirm it. Also, the rep may not have dug into the internals. Seems easy to find out but oh well.
> Tanabe: "Grant
For the Lexus RC and Lexus IS it uses a specific bolt-on exhaust systems that are specific to that application."
> Me: "Hi - Is it more about the performance could be affected or the fit? Interestingly, the RC and IS use the exact same OEM F-Sport upgrade exhaust system. That indicates they fit and performance isn't negatively affected. The RC requires a new diffuser to fit the single tips, but that's all."
> Tanabe:
"Grant,
Mainly because of the fit but not sure if the internals are dramatically different between the two."
If you have any other questions, please let us know."

anybody got pictures or clip of an RC axle back installed on their IS? i want to hear how they sound like lol. is it the same as regular RC? For those doing custom quad tips, why don't you just get an RC350s axle back instead of welding a tip. just wondering.
Thanks in advance guys!
Thanks in advance guys!
We are however looking for a 2017 IS that is willing to come by for us to prototype something new for the community! Spread the word.
