I just installed a 40 series delta flow on my 2007 4.7 Dodge Ram. Its sounds perfect. When you turn that key over the start up is awesome. When you hit the gas it sounds like a beast. Interior noise is loud until you hit about 35-40 miles MPH then it quiets down to nothing. When you hit the highway interior noise is a litle bit louder then stock and it doesnt go away at about 70-75 MPH. But it is worth it.

 

You think you could post a sound clip? I'm going to try and talk my wife into one, except I haven't decided which to go with. I have 06 Hemi QC and I was thinking about 40 or 50. I've never paid for an exhaust, but I've always wanted one. My wifes first truck had duals with glasspack. So it shouldn't be to hard to talk her into it, except for gas prices. Anyways if you could post a clipI would appreciate it.

 

I am not quite sure how to put the sound on here. I will look into it for you.

 

glad you like your 40 series, i have the super 40 on my truck and i love it!

 

I'd like to hear some good sound clips of the Super 40, and the Delta 40 as I'mwaivering between the 40 and the 50 Delta. I want the loud rumble, but not annoyingly so on the highway to the point of a migraine!

I hadtrue dual40s on my 2002 Mustang GT with a Mac Prochamber a while back, and man it had loud growl, and made me smile at every stop light, but the drive to work left me numb and reaching for the Advil! LOL!

Same thing for the Rams or is the 40 tolerable at highway speeds?

eh the super 40 kinda depends, around 2000 rpm i get the growl inside the cab. But anything below that its basically nothing inside the cab To give you an idea i sit at about 2000 doing about 80 mph
