I don't want a loud muffler either. How hi is the tail pipe tucked up there? I've dragged mine a few times as well just figured if I ever pancaked it I would just have to cut some of it off to get home.
I'm looking at at adding a Super 44 to my Commander here shortly. Went by & saw my man who's going to do the install. Looks like 2 1/4 inlet/outlet, and center-out, by his measurement. Will be posting more details, once I acquire said muffler, and get it installed.

Flowmaster 50 Series SUV muffler is the way to go on a 4.7 liter. Hands down....

My Flowsound (Flowmaster knock off) Muffler on my 4.7.
Interior Sound at Idle: Low, rumble
Exterior Sound at Idle: Low Rumble
Interior Sound at Freeway Speeds: 45 ish is a bit loud. Real deep. After overdrive kicks in its manageable. Havent had it up past 70, but im thinking about 75 she will get loud.
Exterior Sound at Freeway speeds: Not sure
Any performance gain advertised vs felt: Not really
Size of muffler vs the Stock setup: just a replacement, I think its a little more tucked under there than the big old stock one.
Overall impression: loud and I love it!! best 80 bucks I spent.

I have the 40. It's only loud around 2,000-2500 rpms from 1st-3rd gear. But my buddies like it. I like it. It's awesome.
I guess its just a personal preference. But I think the 50 series SUV muffler is great on the 4.7 liter. It has a mean sound to it and its not raspy at all. You dont get that loud interior drone like you do with the 40 or 44 series and can actuall carry on a conversation while driving..lol Not to mention how many people that have come up to me saying how great it sounds.

I'm torn between the cheap Thrush muffler or the Flowmaster Series 50. Anyone know which model I need for my 3.7 WK? What diameter inlets and where they are located?
