Want to do WALD rear body kit follow with the quad outlet.

I can't say this on the RX with 100% certainty, but on the handful of cars I've changed my exhaust (some axle-back, some cat-back like Wald's) and no issue whatsoever. My recent project is on my IS and all good. So long as your catalytic converter is not removed, I would not expect any issue. You can always ask Wald if you want 100% certainty.

Thanks! Catalytic converter stays, should be okay.

A simple test for you to try to mitigate any risk before investing in the exhaust is unbolt your current one and drive the car around for a bit. Good luck and keep us posted. Definitely interesting to see a modded RX beyond some cosmetics (extremely rare).

As long as nothing you do to the exhaust causes the 02 sensor to trigger, or cat to fail or be removed (thus triggering the 02 sensor), then no.
