Hi,
I recently purchased a tune. I also purchased a cat delete. Tune was fine. I added the delete and it all started. The cat delete has caused exhaust fumes to come in the cab. Variation in tune doesn't affect it. Letting off gas after a steady speed enhances this. I do have windshields but have opened the vents\varied, etc. For opinion, is it the rear exhaust that is coming back to the cab, or is it the fact the cat delete doesn't use a donut? There is no leak at the turbo that I can tell. Muffler\cat junction seems ok. I have considered having a tail pipe made that extends low and close to the ground. I hate to remove the cat delete and gain all that heat back. I realize what a cat con does, so it may be possible the fumes were always there just not so strong or rich as they were being burned off. Just hard to believe thats the case. Appreciate any experience here. Maybe I am overlooking something.
