Bernd I know a lot of guys ask you questions directly on the board, but you seem to be the guy with all the answers. I am faced with the age old exhaust question: What to buy and why? I like my truck to be loud on the outside (hear me coming a block away), but I don't want it to be annoying on the inside. I've researched the board and all the manufacturer's websites, but I am unable to decide because everyone says something different. Flowmaster 40 vs Flowmaster Delta 40? How loud is gibson compared to the flowmaster 40 deltaflow? Dynomax sound pretty good too, but what's the real diff between them all. I know you may not be knowledgeable in all systems, but could you try point me in the right direction. I know that flow doesn't meani shit because exhaust pulses and is not a steady stream etc... Help me and I'm sure a lot of others out. Thanx.

On the Flowmaster:
The 40 series will have a noticeable resonance in the cab. If you're looking to keep it agressive sounding but somewhat quiet in the cab, the Flowmaster 50-Series Delta-Flow muffler will be the best choice (in the Flowmaster line).
As for the difference between the Dynmax and Flowmaster, the Dynomax is a perforated, straight-through tube and the Flowmaster is a chambered muffler. Both work very well performance wise...the Dynomax, as compared to the Flowmaster, is quieter.
I've personally run Dynomax (SuperTurbo), Flowmaster (40, 50, and 50/Delta-Flow), Ravin, and MagnaFlow. Out of all of those, the 50-Series Flowmaster was the best sounding (slightly loud though - currently run it as well) and the Dynomax was the best sounding (and quietest) at idle and cruising speed.

Thanx Bernd again you come up with an answer I'm looking for. Just a few more things: The Delta-Flow mufflers are listed on Flowmaster's website as being one chamber or two chamber. What's the diff? It doesn't just say 50 series. Which would I use to replace stock muffler and put 3" single pipe front to back? Part number? Do you have any comments on dumping the exhaust out before the passenger tire (pros/cons if any). I really like how the Ford (I know it's a four letter word here) Lightning's exhaust looks. Single pipe into dual side by side chrome tips.
Also are the Flowmaster mufflers durable because I live in Canada and the highways have some salt on em if you know what I mean. Probably not since Texas doesn't tend to see a single flake. Thanx again eh.

You are talking about the Dynomax SuperTurbo when you say it is quieter than the Flowmaster, right Bernd?
'Cuz I had a Flowmaster 40 on my Dak for two days, removed it and put a Dynomax UltraFlow muff on ... the Dynomax was louder and had a more "race-like" tone to it.

Yup...I was talking about the Super Turbo (noted that in the post). The UltraFlow's are REALLY loud! :)
I guess you could call it "Flowmaster Marketing". Going by the picture of the Flowmaster Delta-Flow, that's no 1 or 2 chamber muffler...I count at least 3 or 4 chambers.

But it's their product so i'm not going to argue with them. ;)
If you're looking for a 50-Series 3" IN/OUT: 53055
If you really want to keep it somewhat quiet but still 3" IN/OUT (70-Series): 53070
I've never been to Canada in the winter so I can't say how well they'll hold up. However, I grew up in California (San Jose) and frequently took my old Camaro (with dual Flowmasters) to the mountains (in the winter) to go skiing. They do salt/sand the roads and they held up just fine. Again, not sure how harsh Canada is on the roads though...
I really like the Lightning exhaust tips as well! :)
Hope that helps.

I've got a 2000 CC Sport 4x4 with the 4.7L and a 5 speed. Gonna do the exhaust then put K&N Gen II on it when they FINALLY release it. I want to put the Kenne Bell SC on it, but after exchange and all it would be like $6500 here. :(
You can post sounds if you have a link to them online. e.g.
Z71 exhaust
Just replace the url with the link to your sound and change the text after (Z71 exhaust) to your own text e.g. Gibson.
Here's what it will look like: Z71 exhaust

Hey XLTSPCL,
My truck is the same as yours, I got a Mopar cat-back on my Dakota. On the inside it's just perfect with no droning but you know it's there, and on the outside it's loud. I live in Canada too in toronto, Come check out my web page with all the pics and sounds on everything.

My buddy with a 97 4x4 CC 5.2L 5 spd Dakota just put true duals on front to back with dual 2" stainless and dual Dynomax mufflers yesterday. The mufflers come with a lifetime guarantee. Is it worth it to get them over the Flowmaster Delta 50s or does Flowmaster have a similar guarantee? So many questions...

True duals is not gonna help him unless its seriously moded probably even make him worse lose t/q the best exhaust for these in my opinion is a dual split muffler, 3 inch in to the muffler and 2 1/4 rear exiting duals, use whatever muffler you want and mandrel bends on whatever system

Bernd. Ok I've researched the differences between the 40 and 50 series Delta-Flows and have noticed only a slight differnece in interior noise. Yet the exterior noise is substaintially louder in the 40 series. Since I could give a crap about what the neighboors think I am leaning toward the 40 series Delta-Flow. Here are the comparisons for those of you that would be interested:
My question still is, what muffler configuration to go with: single in/single out or single in/dual out? Is this going to create a problem if the muffler is only single out, not very much room to split to duals after the muffler? Is there a difference in performance? Would going larger outlet pipes on the dual out cause a performance issue when they are only gonna be dumped before the rear tire? 3.25" vs 2.5" with tail pipe being only a foot long at the most with mostly chrome tip like the above picture. Also if single in/single out 3" is the way to go then which part number do i go with to fit under my truck and put the tip, preferably tips, out before the tire. I am ordering the muffler from a connection that gets them for cost, but I need a part number. Thanx again.

If you want loud definitly go w/ the 40 series Delta. The louder the muffler the more interior noise/ drone/ resonance you will also have. If you run a 3" muffler a single 3" tail or dual's will only flow as much as the muffler inlet size, so what ever looks better to you.

Ok, I have the same truck, but with the 5.9L. If you are going with the single muffler and dual exit, you might have to swap out your spare. My 31x10.5 spare would not fit once I installed the gibson split rear system. From what you are describing as your goal (interior vs. exterior noise), I would totally stay away from the flowmaster design. they are down right annoying at highway speed especially since you have a 5speed turning around 2k rpm at cruise? If so, they will drone the hell out of you and it does not sound like an engine but a very annoying tone. This comes from some experience with flows on mustangs and other friends cars. Most with different exhaust designs, ie true duals and Not 40 or 50 series, but there isn't that much difference from the old flows.
My gibson sounds great inside the truck and just lets you know its there until you stand on it. People can actually sleep in the truck while cruising on the highway!!!! Outside the truck it is loud....sometimes real loud depending if the engine is warmed up. I have some wav files from behind the truck I can email that I recorded on my laptop, sorry no webpage.
I say get the gibson or dynomax as they are strait designs and can get them in stainless. the gibson aluminized kit had some problems with fit as there are a few leaks, I think they actually gave me a stainless muffler and aluminized pipes....no tips, and there are small differences in ID/OD that required some modification. Overall, don't take anyones advice without hearing the combo first as that is what will make you happy. Once you hear what you are looking for, you will know it immediately. Tech specs and folks words are helpful to narrow it down, but only you can make the decision of what sounds good to you. Just my $0.02 as I recently went through your same ordeal.

aggie97: My dual exit will still exit before the rear passenger tire so there should be no modification required for it. Is your experience with regular Flowmasters or with the new Delta-Flows? The Delta-Flows are half as loud in the interior as the regular mufflers (so they claim).
Does anyone else have any experience with the differences? Regular 40 series vs Delta-Flow 40 series? What is the highway sound like on the Delta-Flow 40's as most of my driving is done on the highway.
Does anyone have any wav or mp3 files they could send me with their aftermarket exhaust sounds with the 4.7L?

Hey Art, I do know a good system and I have owned a bassani system with x and catback on a 97 cobra. Just because an x pipe and catback are stainless and cost a fortune doesn't emply quality. system quality was OK but I had to dimple my floor boards to clear the mufflers. flowmaster and Mac systems bolted right in with proper clearance all around. Bassani also can't make a muffler and x pipe combo that sounds american on small V8's. If you want an italian exotic sound fine, but for trucks, stick with what we have discussed so far. Maybe that is why bassani does not make a system for Daks!!!

I have used Borla on my old Dakota R/T and I liked it. I used the "Turbo" style and it wasn't very loud inside. Outside it was fairly loud but only at WOT. The performance was the main reason I liked it. I don't like Gibson exhaust and Bassini does make an excellant exhaust for the lightning that includes headers and a complete catback. If you own a Lightning then you probably know who "Lightning Tuner" is and that's what he sells and uses. I've heard of impressive gains with their system. For A dakota MBRP is very hot and I personally like the Spintech Sport Truck SUV #5436 3"IN/ dual 2.5"out. They sound wicked on a Dakota R/T. I have used a Spintech Sportman XL but it was way to quite, even more so than the Borla. For a Dakota I'd lean toward Spintech,MBRP, or a Dynomax UltraFlow. For a lighting I'd go for the Bassini complete system. Both the Spintech Sport Truck SUV and the Dynomax Ultraflow are louder than a 40 series Flowmaster. The Dynomax is more Raspy and racy, but the Spintech is Deep and very throaty.
