Hi Flow Cat

[magicfox32]

Will most any universal hi flow cat work on a 96 LX? I was thinking 2 1/2 inches in/out and all the way back.

magnaflow 91000 series

edit: stock piping is 2" the part number for a 2" in/out magnaflow is 91004

[magicfox32]

Thats the only one???
Where canm I find it?

[95ProLeila]

it comes in a bunch of sizes, goto magnaflow.com. The 91000 series is just the proper setup for a protege so you don't throw a CEL and/or fail emissions

[magicfox32]

Cool thanks, I read a post about melting the inside of it out, and I was like....uhhhh I dont think so, I'd rather pay the 50 bucks and get one.

[95ProLeila]

its a bit more than $50, and I think the melting thing was bs, because from what I understand, the inside is ceramic. . . which doesn't melt

[magicfox32]

I read he torched it, but oh well that doesnt matter because I am not doign that.
Thanks

After my cat the piping is 2.25" and before it is stock. Which cat would I get?

Ok so it's the 91000 Small oval series.

What will a High Flow cat do exactly? What are the positives and negatives?

[magicfox32]

More high end I believe, mabey a few hp. Also it will be louder. A more 'beefy' sound.
Other then that I dont know a lot about em.
Negatives- $

[95ProLeila]

It won't be that much louder. It's less restrictive which is what you want throughout your entire exhaust. The 91000 series is what Magnaflow told me to use on a 95-6 protege. You may want to call them since you're a 97-8, just to make sure.

[magicfox32]

Would I need the first one "91000 small oval"
or the second one "91000 single sensor"?

[95ProLeila]

91004 offhand I'm not sure which one it is.

[magicfox32]

that was the first one without the sensor, and that is at 2" would it be possible to get a 2 1/2? or would I need to match up the size from the header pipe?

[mattbeekler]

How would pulling out the cat and just throwing in a straight piece of pipe effect the car? Wouldent that offer maximum flow? I'm sure its not exactly legal... but i dont have emissions here and its not like a cops going to go up under my car and see it.... :D

[95ProLeila]

you'd throw a nasty CEL. Your car would go into "safe" mode, and wouldn't be much fun to drive.

edit: fox, I would say use all 2" piping, the size is fine. If you're really hellbent on going larger, take it to a shop and see what your options are. I'm pretty sure you can do 2.5" cat on 2" from the header to a 2.5" midpipe, but the piping from the header would need to be expanded.
