(3 inch in/out) 100 cubes per square inch is the highest flowing cat that hasnt been 'modified' available. Still have the stock dump. What can this flow???cheersSteve Link to comment https://www.fordxr6turbo.com/forum/topic/59591-3-inch-zorst-std-dump-5-inch-100-cpsi-cat/ Share on other sites More sharing options...

Thought it would go more than that with the big cat though. Would removing centre muffler and getting an aftermarket dump be worth doing to this set up?

Get yourself a 3.5" single or dual 2.5 and you'll be larfin mate Link to comment https://www.fordxr6turbo.com/forum/topic/59591-3-inch-zorst-std-dump-5-inch-100-cpsi-cat/#findComment-906602 Share on other sites More sharing options...

There's nothing wrong with the cat you have so it will work well Link to comment https://www.fordxr6turbo.com/forum/topic/59591-3-inch-zorst-std-dump-5-inch-100-cpsi-cat/#findComment-906617 Share on other sites More sharing options...
