tony tt Posted June 5, 2009 Share Posted June 5, 2009 Just keep the cat you take out and come mot put it back in for the test mate. Also if you do go full de-cat remember restrictor ring bud or your tubs could go pop! Quote Link to comment Share on other sites More sharing options...
hiten55 Posted June 5, 2009 Share Posted June 5, 2009 most people either find a "friendly" tester, or put the 2nd cat back in as a temp measure... some have even passed without it but the odds of that are low..... Quote Link to comment Share on other sites More sharing options...
