I dont see how people are shooting flames without them if the car is properly tuned?I do remember following a wrx one night and he had flames coming out on every gear change just cruising. 1 Link to comment Share on other sites More sharing options...

Mine doesnt shoot flames or stink or sound much different to a 100cell cat. But it does make more power on less boost. Link to comment Share on other sites More sharing options...

bjc Donating Members 2,812 Member For: 20y 7m 16d Gender: Male Location: Townsville Posted 06/01/12 09:15 AM Share Posted 06/01/12 09:15 AM There probably still restricting power even with twin 100cell cats as they are 4in and next to each other so gas flow is separated etc, not to mention what is the quality of the cat converter to.Aren't 100cell cats illegal as I'd think even though they say or state they are does anyone have written proof that they aren't illegal in Australia and can pass emmissions or whatever is required for them?Who would want to spend $600-$1000 or more on twin cats when a single piece of pipe does a better job for nicks... My opinion. Link to comment Share on other sites More sharing options...
