I was wondering if anybody has done a secondary cat delete on a Is200t or rc200t, I'm considering it but I want to know more before I go for it

 

Do you mean then two small resonator? The cat is single piece but two cat inside

 

on the Lexus is200t models there is a double catalytic converter from what I know, the first one is right near the headers and the second is right after that, then comes the resonators then mufflers

 

Isn't this a secondary cat

 

Does my '14 IS250 have secondary cats? I've been interested in doing this but idk if I can or not

 

if you remove cats on some vehicles it will cause the computer to mess up at certain altitudes and may blow your engines. yes this happened to me in a nissan with 10k miles. it was a nightmare trying to get fixed under warranty...10k for new engine

 

I wanted to take it out because I heard that the horsepower gains are pretty good on turbo cars but I could be wrong

 

Anyone can confirm this that is catalytic converters or resonator? Planing to delete it. Thanks

 

I have a Tsudo axle back with resonator delete. It sounds nice IMO. But I'd like it to be louder, which is why I was wondering about deleting the secondary cats.
Mh friend has his secondary cats deleted off of his Genesis and that thing sounds nasty! It's a deep sound with some pops at higher rpms

 

Let's not forget that its illegal, and you spew harmful chemicals on passersby and people on sidewalks.
Seems like kind of an immature thing to me, I'd maybe have considered it in high school.
There are plenty of ways to increase power and sound without wrecking the air people breathe around you.

To each their own.

 

Deleting the cat on an IS/RC200t would require a downpipe.

STOCK


De-catted downpipe (not smog legal)

High flow catted downpipe (Legal)

The other 2 canisters are your resonators.

 

Might throw CEL, Also upgrading downpipe will mostly require a tune.
