Cat delete question
I have purchased the TSP 1 7/8 long tube headers and the offroad x pipe. There are bung's welded for all 4 o2 sensors. Is there tuning to keep the cel light from coming on or will I just have to live with it?

Your tuner will take care of it, so no check engine light.

You'll get codes for the missing cats and those will turn into permanent codes that can not be tuned out without fixing the problem (you can tune out the CEL light but the code stays and screws your emissions test). I had to buy some o2 spacers and put the Big Daddy mini cat o2 sims on those to convince the car the cats were back on and it removed the codes after a few cold starts. Then I could tune them out. If you don't want to tune the car, just get two Big Daddy mini cat o2 sims and see if your codes go away. If not you may have to put o2 spacers in front of them like I did. I never did try the big Daddy mini cat o2 sims by themselves. I already had the o2 spacers so I just used them both together

Not worried about emissions here in Alabama. They dont test here. Those Big Daddy mini cat o2 sims are cool but I'm getting a tune so I'll save that money and apply it to the tune cost.

I’m just got CA test pipes for mine. Before I get it tuned I’m going to try the o2 sims you linked above in the thread plus a set of spacers and see what happens
