Is there a way to make a smoke switch or something for a 2012 lml. I know people have a lot of opinions on this stuff. But I'm not here to start any big long discussions or anything so please just leave it be if your not in favor. I would just like to know so I could smoke out a few buddies who think they're cool with their old dodges that boil the smoke out compared to my duramax just puffing it. The only difference is I'm backin mine up as where there's is just for show. And that's all I want it for. Not to cause trouble or Anything. So if any of you know anything on this would you please share some info with me?
