Doesn't have to be tested. All the cop has to do is pull you over for a noise violation for your loud exhaust and look up under the truck and see.

I live a few miles away from espanola new mexico and everyone down there runs catless and mufflerless so the cops dont care to much about the noise. im glad haha. i live in a state that isnt very strict with rules like height restrictions and sound restrictions on trucks

if the other 2 are still in the cop wont know the difference. out of all the times ive been pulled over specifically for exhaust only one looked under my truck. i even had one of my neighbors call the cops on me and when the cop showed up she had me rev it and then told me to idle out of my neighborhood and she wouldnt do anything about it. and i live in a pretty big city

You folks apparently live in states (or cities) that are allowing you to do this. Keep in mind however that this is a Federal Law, which over rides any state laws. Stay within your area and it sounds like you're safe. Drive into other states, and you may not be so lucky. Again, Federal law prohibits the removal of any smog equipment.....

its only illegal if you get caught haha

What is a good option for good sound w/o cuting the cats?

I have a f150 lariat 2005.

i deleted my two year cats today and it sounds deep and nice now i love the sound. and i got the gibson dual extreme cat back for my truck before i deleted the cats and its got a good tone to it but its not to to loud. thats why i did the cat delete.

i like the sound of a dumped exhaust....i have a si/so thrush welded dumped before the axle and i like it personally, however i would like to get duals out the back going from the cats back. anyone do this with two mufflers and two pipes or is it a waste of time...maybe just go si/ dual out

i have a 2002 ford f150 super crew with the 5.4 and i was wondering if removing both the rear cat would make me have to reprogram the computer
