If you stay with the standard single 2.75 or 3" pipe, I think you will be fine.:2cents:

No you will not need a tune just for a exhaust unless you were planning on cutting the cats out then you would need a to have you rear 02s turned off

you can get 02 sensor simulator to dummy out the sensor otherwise
