High flow cat guys... stupid question

[Sabz5150]

Just got my Carsound high flow, pretty little piece but I'm a bit confused... which way does it go on the car? Is there a front and a back to this thing? There are no markings on the cat so I'm at a loss. Anybody able to help me out?

[bobafett]

is it a weld in or a bolt in?

if its a weld in, then it doesnt matter, if its a bolt it, it should only go in one way if it will fit at all. i never knew of a true bolt in cat, so i just got a weld in

[shepherd79]

like bobafet said, if it is bolt on it will fit in one direction.

The Catco cat that i got, which was a universal came with the arrow pointing in the direction of the flow imprinted on the heatshield. But IMO it should not really matter, cause its a catalyst comb inside, so the reaction does not have to do with flow. Unless its designed that way.
