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 have my center cat gone, gives the exhaust a LITTLE more rumble. Its quiet when i cruise, but loud enough when i gun it. I wouldn't mind a LITTLE louder though for gunning it.

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.

The look of the mufflers is clean, and if i gutted the cats it would not cost anymore since i could do it myself. Also with the car being a '93 i found out i would not need to deal with the o2 sensors leading to a CEL. What do you think about this idea? Is it worth the likely day of labor to get it up and unbolting the cats? Once i get them down what am i going to gut them with?

Thanks all,

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
