just wondering for all of those with heavy mods on your LS1, when you took it to emissions, did they dyno it or actaully just connect something to the computer, If I'm getting that SLP long tube heades and the SLP loudmouth, will they look at my SS and say WTF is wrong with that thing? I don't wanna get too shafted, can anyone tell me of a good place to go and get this done that won't dyno the thing and just hook up the computer?

 

you wont pass the test with LT's here in chicago

 

you WILL pass emissions here....96 and up use obd2 computer diagnostics.....so that means theyll just hook you up to the computer....i was fine i went with offroad pipes which means no cats...the only thing might be that u dont have cats and they will fail u that way..but when i was there they didnt even look....buy flp headers they have the interchangeable cats and offroad pipes.


good luck
