High flow cats

What have people used for small compact high flow cats. I have come across some "spun cats". I'm not adding them for emissions reasons, but to kick down the interiro noise of my catless X pipe with magnapacks on my 04 GT. This website has cheap cats, but was wondering on their durability.

I don't know the difference b/w the non-metalllic and metallic spun cats. I'm assuming it would be the core material composition.

Thanks for any input. I'm also looking to keep this reatively on the cheaper side. my other option would be to install sound deadener...but a 4'x6' sheet of materials I need (the back half of the floor) would run ~$250 lol

And I like my magnapcacks....so I don't want to switch mufflers lol

Thanks guys!

The metallic cats have a more durable substrate, meaning they can handle more abuse and higher heat before breaking down. Cats are one thing I wouldn't cheap out on, but that's just me. The proven Magnaflow spun cats are less than $100 each.

Dean, when you hear talk of "spun" cats, the exterior shell is usually what is being described not the substrate itself. As master486 said metal substrate cats are better than an equivalent ceramic model for durability. A steel honeycomb structure is more tolerant of heating/cooling cycles and mechanical shock than one built of ceramic. They also work sooner (have a faster light-off) and are less restrictive due to the thinner construction for a given catalyst surface area.

Don't get me wrong, the common ceramic substrates are better these days. In the past so-called "hi-flow" meant larger inlets and outlets. Technology has allowed better flowing ceramic cores. I had Lou's install these on my old SC. No durability or flow issues.

Back in '99 I changed the exhaust on my '92 Sport (long tubes and custom true duals). Per usual I over-thought and over-planned all my options. At that time metal substrate converters were only being used by a few car companies (Mercedes, Lamborghini). They weren't available for retail yet so I had a pair custom made from one of the original manufacturers. Mine had stock cat housings so externally they look like your run of the mill factory cat. The company's website is here: http://www.metalsubstrate.com . Back then they were starting to manufacture the metal cores for a couple of aftermarket exhaust companies (wouldn't tell me who).

Now you can just buy them from Magnaflow or the place you linked to. I plan to use metal substrate cats when I do the exhaust on the '97.

DLF how long have those been on your car when you took the pic? They look like they are holding up well. For $37 a piece I don't know how you can go wrong. Even if they do break down (as long as they don't rattle) they will serve the purpose I want them for lol.

About six months, but they look the same today.

BTW, I have the $59.95 metallic cats.

I got the one piece Magnaflow set from Performance Peddler. I'm happy with it and it was a good fit.

The Parts Bin Special is DEAD! It is being parted out.

What is this "one piece magnaflow set" I went to the site to search for universal fit cats and they asked for a car make/model/year then told me they found no matches lol.

They call it the "Direct Fit" unit. For your Mustang GT, the part number is 49003 (http://www.car-sound.com/02product/d...irectfit=49003), but by the looks of it it's currently under development.

Hmm OK thanks master. I may stick with the spun ones from the site I linked in my first post. Small, simple, and without the Magnaflow price tag lol.
