Cat's Which Ones Better
 

So I'm on Summit looking for a cat to use in my exhaust system that I will be doing and I came upon these two.

My questions are: are they both hi-flow, other than the shape and one being spun is there any real difference becuase the are only $3 apart, and which is better: The truck is 4x4, is a daily driver, and will have Flowtech shorties with downpipes into a y, then a cat then into a Flowmaster Super 10 and duals out the back. :icon_headbang:

Also with the shorties I don't want to use the old downpipe and y pipe, but I have not been able to find a new pair, anyone know where I could look???

I just ordered the 59959 (amazon has it around $75 ;)) for my truck. The metallic substrate should flow better and last longer.

Spent the money you saved on learning the proper use of an apostrophe!

Maine Coon.

Oh, wait.... that's not what you were referring to?

Right then.....

Either one would work. Although, I suspect you could find the first one in a NON-mirrored finish for cheaper.......

Haha funny guys, but I'm kinda leaning towards the spun cat.

Do you even NEED a cat in your section of Ohio?

Yes, sadly I do :(

Federal law requires you have one on any road vehicle originally equipped with one :icon_deadhorse:

Yes, but who cares what the Feds say? :D
