Is the Magnaflow 3" catalyctic converter bi-directional? Like does it
matter which direction you put it?
I didn’t see any flow direction arrow on the thing but there is a very small
arrow of some sor (but I can’t tell if its just somethin or for flow direction)
I got one end welded already and just realized after…(save the ignorant comments)
Let me know
im pretty sure there is a flow arrow on it if i remember mine correctly. ill take a look at mine tomorrow to make sure but it shouldn’t matter at all which way its going. i didn’t pay any attention when i put mine in and haven’t had any problems.
Here’s a pic of the cat (no comments on welding). :squint:
The end that you see at the top of the image is where the flange would
mate up with the turbo downpipe.
not that its bad or anything but if you have a mig there I’d be happy to give you a hand. 
I didn’t weld it; I had someone weld it. And as long as it’s sealed and not
leaking, I could care less how it looks.
Anywho, guess I’ll have to reverse the cat jsut to avoid regrets down the road. 
hahah – you do the fancy blow up window but you don’t crop out hte weld…Gonad you kill me man.
It’s not that bad. :dunno:

Oh trust me, people will.
Who cares which way the bloody thing flows… Just punch it out

haha, nice way to spend $100 on a hight flow cat[/quote]
Same as a test pipe, only not as purdy.
Good for you Gonad for keeping a cat in your car. I did the same when I put my exhaust on. It will keep the noise down and your also being responsible.
It doesnt matter which way you put it on, just slap 'er on there.
What can I say, I love the Earth. :dunno:
ya the earth is preaty cool and stuff
actually a punched cat has been proven to make less HP than a test pipe or a highflow cat.
the broken material the exhaust gas going from a small chamber to big to small fucks up the flow.
and you will still get caught with a punched cat since cops carry heat guns now…

all they have to do is tap it with a stick and they can tell that it’s hollow.
