Performance parts

Theres a lack of info of anyone swapping mufflers, etc etc. Post up some vids of your modifications. When I get mine in, I'll see if I can swap my 16 air intake with this one. Might need some modification. I also never leave my muffler untouched. Let's see what you got. Get those videos rolling.

I don't have a video, but I changed my stock muffler on my 6.4 to a Flowmaster Big Block 2 recently. Install guy had a hell of a time getting it on there, but I really like it. Can feel it opened things up and is still quiet, I am guessing I gain a 1mpg or better but hard to tell since wind has been blowing 40phs for last 2 weeks.. My goal was better performance with no cab noise. The MDS is slightly less with this muffler. It is quiet inside but has a bit of a grunt now at idle and more when on the throttle. This was the only muffler I could find with matching 3.5 inch I/Os other than the Mufflex, which is too loud. Bought it on Amazon for $180 and cost be $170 to install. I had the Flowmaster SUV on my Yukon previously and it was the same, quiet, more throaty on the pedal and better mpgs. My dad has the dual Magnaflows on his 5.7 hemi and MDS drone is much worse, and loader all around. Not what I am looking for.

I was pleasantly surprised the stock set up sounded so good. I'll still change it but magnaflow kinda rubbed me the wrong way.
