4" MBRP Exhaust - Muffler or no Muffler? Your Opinions...

I know there have been other threads on this, but I haven't found any input to suit my current dilemma. I got some cash for Christmas to buy an exhaust for my new truck. Currently running stock exhaust. I'm going to buy the 4" MBRP Stainless Turbo Back system definitely w/o the Cat, but I'm still unsure about muffler or no muffler. I want a good sound, but not overly obnoxious. I routinely leave for work at 4:00 AM so I'm not looking to piss of the neighbors either. What are your alls thoughts on muffler vs. no muffler?
Will it still give me a nice sound with muffler? I'm leaning towards getting it with the muffler as of right now.

Thanks for the input and Happy Holidays!!!

Can't wait to get this exhaust on my truck!!!

no muffler. it isn't loud until you stomp on it. even then it's quieter than a mustang with flowmasters.

I would run no muffler. Mine sound great. You can not tell it till you really get on it. It has good sound around 2000. Not to loud. I also leave the house around 4 am.

Are you drunk? I park mine up behind the house a couple hundred feet and even then I can still hear the thing whistling at 3 am while I'm in the house. Click high idle and it's obnoxious. It was cool for about a month now I just want to get rid of it but I don't have the money

to each his own I guess. It sounds like I'll just have to look up some you tube videos of each and listen to the difference myself. what is loud to one person isn't loud to another

He has a 2006, it won't whistle near as loud as ours.

My 03 screams at high idle. But I'm out in the country so I don't care.. Driving with no muffler I get a spot between 2-2200 rpm that's loud. Not obnoxious. After it 2200 it growls and sounds great. With muffler sounds about the same but the 2k rpm thing goes away. Whistle doesn't change at all with or without muffler

I have to agree that it sounds better without the muffler. My truck has a full MBRP exhaust and it had the muffler on it when I bought it. It just wasnt loud enough for my taste. I'm MUCH happier without it. its pretty quiet until you get on the throttle. that 2000-2200 RPM growl is just coooooool. The turbo sounds amazing when its high idling in the morning. nothing beats mode 5 at WOT though

I think I'm just going to get the kit with the muffler and then if it isn't loud enough for my liking, I'll just order the muffler delete pipe down the road. I can always make it louder if I want to!
