merckx Posted January 20, 2009 Share Posted January 20, 2009 Have you had a look underneath to see if it's leaking/blowing anywhere? Link to comment Share on other sites More sharing options...

DannoSupra Posted January 20, 2009 Share Posted January 20, 2009 should do, i had only first cat in mine at one point, and slapped it on the sniffer, and it would pass emissions! Link to comment Share on other sites More sharing options...
