If my cats are deleted without a tune, I understand that a cel will be triggered. Will that cel give me any performance issues? IE: will my car enter limp home mode? Or will I be ok running like that for a couple months?
The fact that the rear oxygen sensors don't affect how the car runs (i.e. A/F mixture) and that the car won't enter "limp home" or any other performance-reducing mode as a result of anything dealing with the rear oxygen sensors. My answer to the original poster's question was relating to performance of the vehicle as a result of the PCM entering some kind of mode, not performance by freeing up the exhaust.
So I'm posting here because, well, most of the recommended headers you guys have listed here for 5.0 Birds are obsolete or no longer produced. I'm halfway through gathering parts for my GT40 build and the only roadblock I'm hitting is this.
Now that I got the correct cat forward exhaust assembly for the car, I have some options on the cat back exhaust. I have the option to replace the cat back exhaust and mufflers. The rear tube of the assembly below is just a reducer and has no muffler capabilities. As I learned with the two...
i just had my t bird dropped off at my house...looks nice just needs to be washed and waxed.
i was wondering..if i cut off the mufflers out back how much pipe or how long of a tip would i need to fit in place of them and what is the diameter of the stock pipes?
