Cat Conv delete

[Jlively]

I have been contemplating deleting the cat when I put new a new exhaust setup on. Has anyone had any issues in regards to O2 sensors throwing codes bc of this or are they generally fine after taking the cat out?

I have a Cat delete system in mine. Just add one of the anti-fouler for the O2 sensor. I have been running mine for a year now with no CELL light. I also Autocross mine at least once a month. MicroImage sells them

I imagine you one might feel a slight increase in the bottom end but prolly not gonna feel much. I want the slightly louder sound to my exhaust hence why I wish to delete them but I have heard of some people getting a raspy sound in their exhaust unless a resonator is used with the no fouler. Im now leaning more towards just a secondary cat delete and leave the first in place so I wont need the no fouler.

Yea.. I feel no difference in my butt dyno.. I have yet to get my car back on a jetdyno though. I just haven't had the time or interest to see the actual gains. I am sure its a little bit of torque increase, but probably non in the top end. I autocross, so every itty bitty ounce of torque is benificial
