What year? Does it need an O2 sensor plugged into it?

An ebayer named performance-curve has some damn good deals on highflow cats, I just picked a Car Sound up for 40$ shipped.

A o2 in the cat? Ah, I don't think so, I never seen that. It has 1 in the pipe.

I didn't find him , but I saw a bunch of others & all those tube mufflers, straight through design. I wonder how loud 1 of those would be on the GA. ?

Thank's, all kinds of stuff there.

I'm just wondering if between a cat & or a straight through muff. this might be removing some nessesary back press.

I might put a gauge on there & measure it.

meh, the difference between a straight through cat (basically a pipe) and a highflow cat is like a pony, and thats not enough for me to worry about, even though every little bit helps. The reason I stick with cats is the legality issue, ive heard of guys getting busted for not having one, and failing emmisions, I figure, do it right or dont do it at all...
