Mini Maxx V2 Delete Kit

All-in-one describes the idea - tuner and hardware in one box - not a fixed parts list. Every bundle includes EGR hardware and an exhaust section, then diverges by platform: the 6.7L Powerstroke and LML Duramax packages add CCV or Gen-2 CCV hardware, one 6.4L Powerstroke bundle adds an up-pipe, and the LMM Duramax bundle adds a downpipe and up-pipe. One LML bundle steps up to a 5 inch downpipe-back dual system. Compare the contents of the specific bundle for your platform, because two similarly named kits can ship different hardware.

2015 is a split year on the LML and the two versions use different hardware at the downpipe. The 2011-2015 downpipe is secured to the turbo-direct pipe with a V-band style clamp, while the 2015.5-2016 uses a 3-bolt flange. Ordering by model year alone is the most common way to receive the wrong connection. Check the actual joint on the truck or confirm the build date before choosing between the two LML bundles. The 2015.5-2016 package also does not fit Cab & Chassis trucks.

Check the PCM software first. The Ram 6.7L tuner supports the original PCM software whose part number starts with a number; a truck that has had a dealer reflash or a module replacement may be running software outside that support, and the tuner will not work with it. For 2018 Ram trucks, the Cab & Chassis bundle ships with a bypass cable, so select the combination that matches your truck rather than assuming the standard package covers it.

It is mainly a sound decision. The straight-through 4 inch race pipe is the most direct path and the loudest result, while the 4 inch race pipe with a muffler keeps the same layout but makes the truck far more usable on long highway days. Neither changes the fitment. The Powerstroke systems are T409 stainless, which is magnetic and chosen for corrosion resistance, so do not expect a non-magnetic stainless.

No. Removing or disabling emissions equipment on a vehicle driven on public roads is prohibited under US federal law. These bundles are sold for off-road and competition use only. A street-driven truck is better served by keeping its factory equipment in place, or replacing a failed component with a compliant replacement part.
