Easiest DEF delete ?

I deleted mine a few months ago. Purchased a MiniMaxx tuner and EGR/DEF/CAT delete pipe from Rudy's diesel (around $1K). It took two guys around 6 hrs (no rush) to complete the whole process. I decided to remove the cooler after a courtesy call to WI DMV and verifying that I do NOT need emission testing. That was in Oct 2016. Now the law has apparently changed and I can't renew plates without passing an emission test. Otherwise the truck's been running great since then, no issues yet (except for a death wobble). Although everyone claims an increase in MPG, mine dropped from 14.9 to 13.9 and staying there. I can't run a higher tune (still stock) since pyro readings cause the tuner to defuel (the OEM pyro probe doesn't communicate with MiniMaxx - readings vary from 32 up to 2600).
Btw did anyone have issues with passing emissions in WI?
If I pass I'll get new pyro kit from Rudy's, otherwise everything has to go back to stock I guess.

evidently emissions testing in my area has changed sense the last time i looked into this , inspection stations are now required to do a visual inspection top to bottom , this really sucks. I was told a story today about a local guy that just got a fine for $10,000 for having his truck deleted . I find it kind of hard to believe that the fine was 10grand , but like i said it was a story, could be true of false info. Anyway I guess I have some decisions to make about this delete I want to do . This makes me so angry .

I hear you, this engine is amazing once it's allowed to breath. Anyone who says they are just as good with that crap emissions system has never enjoyed it without I'm guessing. I will never own another diesel with that crap. I will go back to gas if deletes are ever outlawed. Luckily my area had no testing and my local dealers are pretty delete friendly. So far 50k thou and no warranty issues whatsoever. Most modern tunes don't "roll coal" either, they are usually pretty clean. I have to try really hard to see any smoke and I'm not even running the smoke limited tune I have.

I just researched this. While I cannot comment on the fine....you indeed have to go through a visual inspection where you live. Here we go......You can hallow out the factory exhaust pipe. Just make it look as standard as possible. EGR is tougher. You have a whole host of inspection sites in your area.......go talk to them and get an idea of how tough they are.....many or mom and pops so a case of Yuengling falling out of your tailgate may help.

Anybody here actually install this kit? I've seen it mentioned several times but haven't seen anybody actually install it.

I second this question. If I remember correctly they have a muffler that's almost an exact fit to replace the stock system. I wouldn't mind a minimal increase in exhaust sound but don't want anything loud and for sure no increase in the inside of the cab noise.

I opted for the straight pipe to see how loud it was. Minimal noise in cab if any. Noise by exhaust is noticeably louder but in a good way. Not obnoxious but you definitely hear the turbo. I like it.
