high flow cats or off road Y? I have an 2002 a4 T/A ram air with slp long tube headers, slp high flow cats, loud mouth cat back, is there any difference with or with out cats as for sound and power? and what would be the best next mod for my car? as in gears, heads/cam, stall converter? not really an expert about this stuff

Cats help keep the rasp down HUGE - I have had an off-road y-pipe for a couple of months now and I am pretty sick of the rasp. So, I just bought some Magnaflow spun flow cats to fab up in there
We'll see how that works out ...
