Here is a short cell phone vid of my mbrp 4" on the excursion. It really sounds good under load at speed. I think you will be very happy!

Mine is straight piped; (we don't have inspections in MD on diesels........yet!), and I don't really notice that much noise in the truck unless I am really pushing it mostly pulling my 20' enclosed trailer or pulling my Jeep.
Guess maybe I'm just used to it now?

I just got done installing an MBRP 4" on my Ex. What a PITA! 
Worst part is the pipes are heavy, and lining up everything (don't even try to install the down pipe without help). Getting the down pipe in was a puzzle in itself, trying not to tweak the flange.
I used band clamps from NAPA so as not to crimp the pipes. Removing the passenger rear shock was also a big help.
The truck now is quiet inside compared to the stock system. I would have thought otherwise.
Oh well, time to cleanup and tend to my wounds after this 2 day battle.

Anyway, good job. Put your feet up tonight and enjoy your new exhaust.

My wife did not help, key difference. 
I struggled for at least an hour trying to figure out how to get the down pipe into position, and another 1.5 hrs trying to get it to line up with the turbo. I packed it in at midnight. This morning my wifes foster daughter helped hold up the DP and it was lined up in less than a minute. Yay! (I hope the V-Band clamp is on correctly).
I was trying to make sure that no parts were hitting the body, also. So I took my time aligning the system which took a while. Looks like I had about 1/4" - 1/16" clearance on the DP to this plastic heat shield near the trans pan. At least if the DP hits anything there isn't a knock sensor to go off! (Been there, done that).
I'll give it a few more heat cycles before checking and re-tightening bolts again.

Good read......I haven't done exhaust because I am afraid of the dreaded "drone" at a highway speed......I guess " not too bad" is relative to the owner.....anyone do a Magnaflow ? .....claims are that they are quieter.

I am happy with my stock exhaust but it is getting some pretty serious surface rust... I will probably change it out to whatever the quietiest stainless aftermarket system is. Kinda disappointed that the stock one is rusting so bad. Nothing else under my truck has a spot of rust on it.
