Oh boy lol. Personally I like either Magnaflow or Gibson. I wouldnt shell out the coin for the manufacturers cat back system, this is only the muffler and all prebent pipes etc. I would find the muffler I want and go to an exhaust shop and have them bend and WELD the pipes and save a couple hundred in the process. I checked out the prices on some of those cat back kits and WOW. I bought a Magnaflow for my Dodge from a muffler shop and the muffler and installation with 2 turndown tips ram $175, would have been another $100 or so for pipes to be ran. Same Magnaflow kit was well over $500 at the time.

 

On the WickedFlows, you can get them at Untitled Page

You want the Max Series. From there is a matter of which pipe size and case size you want. The larger the case, the quieter it will be.

In response to the videos, the only video I posted that was a V8 was the Maurader. But here is an F-150 with the 13" Muffler.
YouTube - WickedFlowMAX 13" on 2006 F-150 5.4L Idle to 3500rpm

In this video the exhuast does pop a bit when he lets of the gas, this doesn't happen when it is in gear.

 

The closest thing in that video resembling a rumble is the pops. If quite is what you are looking for, go to any auto parts store and buy a stock muffler. If youre feeling like a little rumble, here is some clips of both Magnaflow and Gibson on a 4.6 liter:

YouTube - 97 F150 4.6L No rear cats, SISO Magnaflow


Gibson
YouTube - F150 Exhaust

 

Video 1 is an illegitimate comparison, the rear cats have been removed. That means you are not comparing equal systems. The Gibson exits in front of the tires, making it louder, also not an even comparison. If you brought a WickedFlow out in front of the tires, or ran it without the rear cats it would be louder too. Lets bring actual comparisons to the table please.

Since I posted videos of Tacomas, lets compare two otherwise nearly identical Tacomas.

YouTube - Wicked Flow muffler on a 4.0L 2010 Tacoma DC

YouTube - 2008 Toyota Tacoma Magnaflow muffler 4.0 V6

I know which one I would pick. BTW that Magnaflow System looks like it has a WickedFlow tip. Kinda interesting, because even though the Magnaflow seems the quieter of the two in the video, the Magnaflows are the ones with the reputation from droning inside the cab. In fact, thats probably why the Magnaflow system has a resonated exhaust tip, its probably and effort to reduce droning.

 

Your videos of the Tacomas are nice and all that, but as far as your speal on comparing apples to apples, the OP has a 4.6 liter and could likely give a rats **** about what a Tacoma sounds like. Magaflows are not known for in cab drone, Flowmasters are. I have a Magnaflow SI/DO on my 4.7 liter Ram, dumped just behind the muffler, and have no drone what so ever. Everyone is entitled to their own opinion, and you like your Wicked Flow mufflers, I happen to think they sound like someone farting across the open lid of a coffee can. Oh yeah, in case you missed it, the OP has pretty much decided on a Magnaflow, is just having trouble finding the cat back kit for his particular truck.

 

That's not a good comparison ether!
The first video is in a garage. The second one is outside.

Lets face it,
the first one sounds just like one of them ricers with a big fart-can muffler.
Also,
Magnaflow make many different size mufflers that all sound different.
You can get one as big as stock I think. And it will sound close to stock...lol

 

Then how come I have to run two Magnaflows on my mom's van just to make it not painfully loud (an 18" and a 14"), but it only takes one 18" Wickedflow to produce no drone at all?

Ricey is entirely an opinion, besides, these are V6 Tacomas, not big meaty V8s. Often what it sounds like depends on what its on. Ricy is a matter of opinion. And I agree, to do a truely 100% fair comparision, you would need to run under completely equal environments with idetical cameras, or the same camera. I was not aware when I posted the video that #1 is inside a garage.

Regardless, a ricey sound is an opinion, what makes the Magnaflow not sound ricey? The two mufflers are built on the same concept. The main difference is the WickedFlow has a tamer sound with less droning and is better made and flows better and has a better warranty and costs less. Thats quite an accomplishment.

Please don't disagree with me on the quality issues, or I will just show the pictures I have of the many ways Magnaflows fail. I don't have any pictures of failed WickedFlows because to date I haven't seen one, but if you have somehow managed to get one I'd love a copy.

I have to admit that I was a bit leery of Wicked Flow at first only reason being I have not heard of them. After listening to my muffler guy who has installed three previous mufflers on my two F-150’s and Mustang, from Magnaflow to Flowmaster, I went with Wicked Flow 3 inch on my 2007 Ford F-150 5.4 I am extremely happy with performance and sound. PERFECT cant say any more they will be in the top three soon.

BTW, Frank, if you are reading this, I would love a video of your truck.

 

I would love to see the fail pics. I can't speak on drone of Wicked Flow mufflers as I've never owned, or ridden in a car with one. I can however speak on drone of Magnaflow. As stated before, I have one on my Ram in the best circumstance for drone to occur, dumped immediately after the muffler and experiance no drone at all. What I like about my Magnaflow is that its quiet at idle and produces a nice deep rumble when throttle is applied, it doesn't scream and its not obnoxious. Also stated before, I can only comment on that and Flowmaster, which I have had on my 4.6 liter. After having the Flowmaster I was looking for something 80% the opposite in terms of tone and drone.

 

If we all liked the same thing,,,life would be boring.

How do they flow better?
My magnaflows are 3" straight through mufflers.

 

Not always. Some of their mufflers are straight through with mandrel formed internals, others are not. Those that are not have wrinkle bends, which creates turbulence, which can reduce power. If the Magnaflow is truly straight through, then the flow will be very close. But from a well respected name brand like Magnaflow, you would expect them to always use the mandrel formed internals.

Fine enjoy the pictures.

I find it a very curious thing that you are so quick to jump on and beat down something you have never tried, especially when the OP was asking for something that was quiet. You put a Magnaflow of equal body size up against a WickedFlow of equal size, the Magnaflow will always be louder and drone more. Basically WickedFlows are ideal for those who want something thats only a little louder and better sounding that stock, without being loud exactly. Everyones perception of loud might be different, and some vehicles are inherently more prone to droning. But nothing is more prone to droning than vans and SUVs, and other vehicles with large interiors. What might be fine on a single cab truck may be over the top on a crew cab, or a SUV.

I have run Magnaflows, Flowmasters, and WickedFlows on my vehicles. The Flowmaster was a 50 series. The Magnaflows by far droned the worst. I ran Magnaflows on both my mom's van and my Mazda B2600i pickup. Both were obnoxiously loud, though at the time I had it installed, I liked it on the truck. But it grew old. I Because of my past experience on my mom's van, I ran a Flowmaster 50 series, which droned a little, but was not that bad overall, certainly within the tolerable levels. The two things I didn't like about the Flowmaster, was the tone changed little with RPM, it was just kind of a hollow but deep sound all the time. But at certain RPMs, it sounded particularly hollow, which being a Flowmaster, its because it was. It also frequently set off peoples car alarms as I drive by. But I started hearing from my customers who were installing WickedFlows that they were expecting them to sound like Magnaflows, but were instead finding they were quieter and had a unique sound. It was after hearing on on a V6 Accord that I decided to try one on my brothers 1997 Aerostar which needed a new muffler. Sure enough, it sounded better, but did not drone. I get an interior sound level of 76 decibels at 65 mph on the highway (stock is 78 decibels at the same speed). I then repeated the setup on my van, and was pleased with the results. I did not get a sound recording of the before and after with my van, but I do have recording with the Flowmaster. My mom just got a new to hear van, a 1995 Aerostar, which currently has the stock setup. I will get some sound clips of it as it is now, then when it comes time to replace the muffler, of the after results with it.

 

WOW, OMG, let me run to the muffler shop and take my Maggie off before the neck breaks. FFS, that has the potential to happen to any muffler. Now, just to keep everything even and compare apples to apples and all that, lets see your fail gallery of Flowmaster, Walker, Gibson etc etc. Apparently to obtain pics such as these you must work in or closely with a shop (maybe in you Wicked Flow muffler sales j/k), therefore you surely must have pics of other failed exhausts. I know 99% of the population dont just run Magnaflow. I knnnoooowwww there are Flowmasters in there somewhere. I had one rust out in a year or so on my 4.6 liter, and I live in Louisiana where snow and ice is only heard about on the news.

 

Speaking about fart cans , thats what the ricers use down here , a magnaflow with a big tip , thats there fart can , if you wan't your truck to sound like some bad *** american muscle , put a cam in it & use super 44s , other wise go to midas, JMO...Lew

 

If you go with the single after cat system beware of the factory Y pipe. There is a known issue with it that is terrible for flow. The right side basically goes straight back and many times where the left side enters there is a very small rough cut hole in the right pipe (looks like it was torched). I cut the factory Y out and used an aftermarket Y, then bolted my Flowmaster cat back on that. Sounds GREAT with no drone whatsoever.

 

There are a Flowmaster picture in there. The shops don't bother keeping them though. Flowmasters don't really come with any kind of warranty cause it a simple fact that they just rust out. So failed Flowmasters go straight to the scrap bin. The Magnaflows come with a lifetime warranty. So the shops hang on to them to try to see if they can get them exchanged. Sometimes they do, sometimes they don't. The manufacturer will only take so many back per distributor per month.

I haven't seen a Gibson fail, though I'm sure they must. Gibsons aren't very popular in Salt Lake, no Gibson distributors. Walker makes OE type mufflers, no body cares if an OE muffler rots out, thats almost expected. I have not seen a Dynomax fail other than from getting crushed. I do have a picture of a TRD on there, who makes TRD by the way? I think they are made by either Borla or Corsa. Those aren't that popular here either, too expensive and they have no distributor in Salt Lake.
