hello all, back again to ask about this specific Borla axleback that i found online:

https://shop.redline360.com/products...be3cb5a343c82a

It says that it's only for a gs 3.5 v6 and is for both RWD and AWD models. Thing is tho is that the IS version of the borla axleback is exactly the same from what i can see except for a cut and clamp on the passenger side exhaust and the tips (I'm planning on cutting the tips and getting a quad tip setup going so idc about those) and its almost $100 more. Do you guys think I would be able to run these on my 2016 IS?

here is the IS version:

Thx boys!

EDIT: also while I have y'all here if u guys have any other axle back suggestions for converting to a quad tip/ actual quad tip setups that aren't going to break my wallet I'd be happy to hear them :] cheers.

The IS and RC axlebacks are the same.
The GS has it's own platform and if I remember correctly the exhaust is too long.

The RC is a GS front, IS Convertible mid section, and 3IS rear...that's the chassis design I'm referring to.

This is true
