I recently did headers and cats on my 05' titan. I had a shop do the cats and connecting pipes and there is still a leak. I'm not sure where the leak is if it's at the headers or where they connected the cats. But I was just driving down the street and my truck backfired. Could an exhaust leak caused a backfire? Or maybe my AFR's are off? If anybody can help me as to why I am having issues with it's backfiring please let me know.
