Brandon123 Posted December 13, 2024 Report Share Posted December 13, 2024 First off, yes I know it is less than legal. Second, what is the easiest way to remove the muffler and/or are there any ways that are a big no no? Third, how difficult is it to reattach the muffler after it is removed? Fourth, is it even possible to reattach it, in a way that will make the car inspectable? Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted December 20, 2024 Report Share Posted December 20, 2024 Engine is tuned complaint to the OEM exhaust back pressure. From what I've read, modifying the exhaust changes timing (slightly), I think it changes the fuel trims, and the emissions. Believe the engine scavenging is based on the back pressures in the exhaust. Don't know if or how much the systems can compensate. As for how hard, crawl under car and look for yourself. (Dont know what your mechanical ability is.) My recommendation? Don't. Lot of work and you can't drive the car on the street. Quote Link to comment Share on other sites More sharing options...
Brandon123 Posted December 23, 2024 Author Report Share Posted December 23, 2024 (edited) Most my mods aren't street legal. what's one more gonna do lol. Would a change in the timing cause the exhaust to pop? because that's exactly what i'm looking to do.

Would a change in the timing cause the exhaust to pop? because that's exactly what i'm looking to do. popping comes from excess fuel in the exhaust, AKA running rich. I suppose changing timing could do that but I wouldn't rely on that as a way of forcing it because I am not sure it would work. I would think removing the cats is more likely to cause popping than removing mufflers, because the cats cannot burn off the combustion components if they are not installed. Also, you could cut the exhaust at a point that is straight for 6"+ and then use clamps to put the mufflers back on as needed Quote Link to comment Share on other sites More sharing options...

Wargrave Posted January 9 Report Share Posted January 9 What year/model do you have? I ran almost a year without a muffler or resonator on my 13 ecoboost. https://youtu.be/CX59Xu08_kY?si=K6zmwCHdqUNOqLFH Quote Link to comment Share on other sites More sharing options...

If you're somewhere that does inspections and need the muffler for it, the easiest way to have it done would be to have an exhaust shop add a flange on the exhaust before the muffler where they cut it off so you can bolt a pipe to the flange or the muffler can be bolted back on for inspections. The v6 seems to drone alone without a muffler though. Quote Link to comment Share on other sites More sharing options...
