FAQ
Q: Can I install this 4" Full Exhaust without a tuner, or will it throw codes?
A: No, a delete tuner is mandatory. Removing the factory system eliminates emissions sensors, which will instantly trigger a Check Engine Light and "Limp Mode." Pair this exhaust with Mini Maxx Tuner V2 to shut off the sensors, clear all codes, and safely unlock your truck's full performance.
Q: Will this 4" full exhaust fix the fuel dilution and oil dilution issues caused by regens?
A: Yes, when paired with a delete tune. The hardware removes the DPF, and the tuner shuts off the regeneration cycle, eliminating fuel dilution at the source.
Q: Does this kit include the turbo downpipe, and will it bolt to my factory setup?
A: This is DP-Back system replaces everything behind factory downpipe. If your stock downpipe is rusted or want to upgrade to a full turbo-back setup for maximum airflow, you can pair this kit with matc downpipes: 15-19 4" Downpipe or 20-24 4" Downpipe.
Q: Is it too loud inside the cab without a muffler?
A: It delivers a loud, aggressive external rumble under acceleration, but interior cabin drone remains manageable at cruising speeds. If you do heavy towing daily and prefer a quieter, more refined ride, we recommend adding an optional 4" muffler.
Q: Will this system drone heavily in the cab when towing my 5th wheel or trailer?
A: 4" system cabin noise is much quieter and more manageable compared to a massive 5" Exhaust Pipe. However, if you pull a heavy 5th wheel daily and want total cabin silence, you can easily add 4" muffler. It tames high-RPM drone perfectly without restrict performance.
