I notice it doesn’t have the baffle like the stock. Does that not throw codes?

The in line post DPF plug in module included in the exhaust kit modified that post DPF sensor signal and calibrates actual to a new modified output that keeps the CEL from activating. So far, 40 miles and no codes with in town traffic and highway driving. So far, so good!

Comes with this lil guy that prevents codes.

Looks just like mine, I guess I installed it correctly.

Awesome. Because I love the look.

Just got back from my trip out west, 6600 miles and averaged right at 11 mpg. Wonder if the intake and exhaust would make a difference? Towed my 27’ Airstream the whole way and don’t see any adverse affects from exhaust heat.

I bet it does, I was getting 13-14 mpg empty and installed the DPF back, derringer, intake and petal commander this week and now empty I am seeing 18-20 here in the high elevations. Sounds stock but wow does it respond now

I just did a Central Illinois run from Texas with Pedal Monster (Sport level 5), Derringer level 3, DPF back and NextGen valve body towing my 27FBQ Airstream and average about 14-15 mpg…Arkansas and Missouri had some decent hills to climb but likewise gotta come down them too. Throttle response seemed more lively with the DPF back. First trip for the DPF back and for me it was noticeable improvement.
