Hey everyone. I have an IS 350C and have wanted to really hear more of the engine, but I've been leaning against a resonator/muffler delete. I love the tone of the F-sport exhaust, but they're pretty much impossible to find, and there are no other options unless I want to import a kit from Japan. I have found someone who apparently was able to bolt-on without modification the Q300 Invidia catback with the Invidia midpipe to their IS 250C, so I just wanted to ask here if anyone can corroborate that that would work for the 350C. Thanks!

Hello!

The exhaust configuration on the IS350C and IS250C are identical. Regarding the sedan though, the IS sedan is ONLY compatible with the IS convertible at the header and midpipe. The axleback between the sedan and convertible are different.

With that being said, the Invidia midpipe will fit on your car, but the axleback will require modification from an exhaust shop (cut, bend pipes, weld). If you look at the back of the car as well, the convertible and sedan exhaust exit at the axleback is different.

There are only a select few axleback exhausts that fit on the ISC, so most people will go custom for the axleback for these cars (which includes muffler delete).
