Trying to help my father in law pick out a muffler for his 03 1500 4.7L QC 4x4... he wants a deep sound and likes the classic "crackle" on decel. That makes me think he would like a Flowmaster original 40 series... Any other suggestions?
What is the stock size and config of these trucks? single in/dual out? 2.5"? I need to know what size to order.
Ok, we will take to a muffler shop to weld in place... and he would probably like single in/dual out and have them run some pipes out the back. Do we need 2 1/2" or 3" muffler?
A straight through muffler (magnaflow, dynomax, etc) will give you more of that "crackle" upon decel sound as compared to a chambered muffler (flowmaster, stock, etc). They are also typically quieter at idle/low throttle and only loud upon heavy throttle and higher rpm. Resonance can become an issue though at low rpm/heavy load. But this is true of all free flowing mufflers.
^^^^^^ What Sean said. I don't know right off hand what size the pipes are, but if you're gonna be taking it to a muffler shop, he'll know exactly what you have and what you need.
I got the Magnaflow 14" Duel In/Duel Out and love it. I have the pipes dumping in front of my RR tire. Sounds great cruising and at idle. But when I get in it, gawd, it makes my nipples hard.
I'd go with the Magnaflow over Flowmaster if it were me. They have a decent sound at idle, BEEFY sound at WOT, and will still allow for a little of the exhaust crackle on decel.
I'm going to be honest, the 4.7 sounds AMAZING with a Spintech SUV muffler. I love it, now I have a hemi and I truly miss the sound of the 4.7 with a spintech. It has the cackle you are talking about, a very very nice one, oh man I miss it. And it has a good classic sound without the "muffled" sound that mufflers like Magnaflow have. Flowmasters have a lot more cackle than the Magnaflows, the tinny cackle is an effect of a welded muffler for the most part.
And, just so you can see that the 4.7 sounds way better than the Hemi, here is the Spintech 3" SI/SO SUV muffler on my hemi engine some time after the swap, before I went to a borla. The spintech muffler is for sale by the way lol
The 4.7L does sound great. I put an aftermarket y pipe on my ram 4.7L and a 14" straight through muffler (no name brand) and it sounds amazing. I have just very slight drone at 70mph+. Here's a video from my cell phone(doesn't really pick up the full sound). It's actually significantly louder in person.
Thanksgiving weekend I'm redoing my whole exhaust. I'm getting rid of the cats, and swapping a 22" magnaflow muffler(y pipe inside), and it will all be SS and mandrel bent. It's all mandrel currently, but not all SS. I don't mind how loud my current setup is but I drive A LOT so even though the highway drone is minimal and not really an issue, it really can suck on those long drives where you have a headache or are hung over or whatever you know lol. I knew my truck was loud but didn't really understand until the wife and I switched vehicles one day and I heard the truck drive off, I honestly felt bad for my neighbors at that moment lol.

i put a flowmaster super 44 on my 03 4.7 last year before the truck was totalled. it was SI/DO with 2 pipes out under the rear bumper. it took about 1,000 miles to fully break in but it was very aggressive sounding and had a nice deep pitch. i loved it.
