Re: Where should i put my dumps?

you have precats and a regular cat, The 02 sensor after the cat is looking for a certain mixture that would let it know the cat is in good condition. places like jegs sell the sensor bypass for like 30-50 bucks... and since your obdII you dont have to run on the rollers for emissions, just no light and your good.

Best place for you is right before your cat, after the first 02 sensor. and then trick the second sensor.

awesome. Shop around before you install. You can find good deals for installs if you play those scam artist muffler shops against one another.
