Looking to put an AirAid MIT, performance muffler, and tune on my 2013 6.2. What has everyone that did these experienced as far as gains in mileage? It's got plenty of power. Just looking for a lil more MPG.

On that note. Best muffler? Looking for something close to factory.

if you want something similar to factory, keep the factory muffler IMO. Otherwise, just get a long case magnaflow, 22/24" case. Stock should have plenty of flow unless you just want a different exhaust note.

I go out of my way to buy a used 6.2 muffler :shrug: 3.5" and sounds great. Most people who i buy them from often want them back.

Put some LTs on it and let BBP tune the truck.
