Post here's something I found on Magnaflow

Ok, first of, you CAN run true duals with the stock converters. Anyone who says otherwise has never actually taken a look at how your vehicle is set up.

Secondly, you can get better cats than Magnaflow. Magnaflow is nothing more than a private label on an otherwise worse than average converter. There are several brands that are better. Magnaflow uses cheap Korean steel, and it is about 50% thinner than what other brands often use. It will offer you no sound or power gains over the original converter in your application, unless your original is plugged.

There are no gains to be had by going with true duals. And any benefits would be negated by the fact that you then have to run two mufflers, and two pipes, so it costs more, and weighs more. You can get just a good a sound by using a dual outlet muffler and running two tailpipes. It also delivers more power and costs less.

My advice is to leave the stock cats alone. They are not restrictive, and unless they are damaged, there is no reason to replace them.

If you did want to replace them, we have cats that work really well for that. Our part# 1005 is larger and less expensive, longer lasting and better built than Magnaflow. As a result of its larger cross section, it flows better and sounds better.

The Magnaflow you have selected is a smaller cat than their standard series. The 94100 series is one of Magnaflows economy products, and is best suited for older smaller vehicles. In contrast, our 1000 series is designed with trucks in mind, with special attention to flow, load rating, and sound. It has 30% more catalyst than the equivalent Magnaflow, 25% more airflow, and more than double the lifespan.

On the subject of the muffler, the kit is overall good and should last a long time, and has a good sound. However, the mufflers are made of the same Korean steel as their converters, and the mufflers often eventually break around the necks, often on both the inlet and the outlet. I would consider a Borla, Flowmaster, or Dynomax instead.

Will have to find what CAT they're talking about.http://www.bearriverconverters.com/

I did the hi flow cats along with a cat back exaust and some shorty headers and CAI with custom tumes so I can't tell you the differnce alone but it deffenetly has a nicer rumble to it and all those Mods together worked well

I've had my maggies since May , but had them done around the same time as other mods so I cant say if there was a quantifiable gain or not but the sound is much deeper at idle and normal driving, gets a tad ricey when you stand on it but thats cuz mine's a v6 not an 8 but so far I love them.


Whaddya mean I dont pay my bills?? Whydya think I'm broke!!

I just pulled the cats completely out of my 04 f150. Definately got more sound and more power, and the dyno proved it.
