I just want to vent because emissions tests are a PITA . I just put cats on the other day and they will be on for about a month then once I pass the test they will be off for another 2 years . The only reason why I take them off is cause I love the way my rig sounds with out them when they are on its still kinda loud but looses all of its growl. I can't wait till its 25 years old cause then it will be exempt. Emissions tests are a joke here any way cause every one I know just cuts there gas with a little alkyhal and if they run a carb leans it out then throws cats on, then when they pass just put every thing back to how they had it.
