Cat delete?
Hey guys, Can you get that v8 rumble from an sc400? Do i need to delete my cats and have just straight pipes? or what? If i delete my cats, i need that o2 sensor cable so that my check engine light doesn't come on right? Anyone know where i can get that from?
Thanks,

I already have my resonators deleted and that third cat. I want it louder though, like the old vettes.

Johnathon...deleting the cats will definitely make the car louder. The key to a loud exhaust is few bends and few restrictions. I am not sure how many oxygen sensors attach to the cats, but you will need to get them welded to the down pipe that will need to be fabricated to prevent a CEL (check engine light).
I would think that deleting the mufflers rather than the cats would produce more of what you are after. There is a video of an SC400 without mufflers from a few weeks back. It definitely rumbles.

Have you looked at a Lexus cat? From recollection, they are no restrictive at all. I suggest an X pipe with mandrel bends, delete 3rd cat, mandrel bent dual piping all the way back to Magnaflow 14829 mufflers. This is what I used to have and people told me it sounds like a souped up mustang. I am sure there are still videos of it on here I posted.
As for the cat - legally you only have to have 1 cat per pipe - so technically deleting a 3rd cat is not violating any laws

Im thinking the first 2 cats. are to help it warm up faster, then there is no restriction, as long as there working right. Which brings us to the next question. How do you know the front 2 cats. are opening up when hot?
