I have cherry bomb resonators no mufflers and my car still isnt that loud im thinking of taking of my cats, but what about the rear 02 sensor im sure it will give a cel if i dont put it back in but will the car run any different or what?

You will either need a handheld tuner or MIL eliminators to keep your CEL light off. The car will run alirght though because only the upstream o2 sensors influence how the car runs.

that will for sure make it loud... and ya u can just live with the cel on or do what he said above^

......or spend a little bit of money and get an o/r H pipe. That way you can put the stock one back on when you get bored of the sound or for emissions. You can also cash in your old cats and pay for half of the new mid pipe. Just my .02

I bought my O/R pipe for $50.

Made my MIL eliminators for less than $5.

I can live with the check engine light till i do my h/c/i then when i have to get it tuned it will be a good time, i think ill be happy with the summit knock offs and the new sound! thanks boys!
