I got a 4.6 v8 in my 2010 stx. Ill be doing a dual exhaust set up soon but I can't get a loud muffler. So I was thinking about doing a electric dump just before the muffler so when I have mt friends in my truck or just me I can have it wide open. Would it trip and codes or make the engine light come on? I would still have the cats and everything. I would just dump it right before the muffler.
