Hello I currently drive a 2002 civic coupe , as my daily driver . I just installed a header and test pipe and have error codes coming on . My question and concern is how do I pass emissions with out spending too much money or having to remove the headers / test pipe ?

What are the codes?

P0420 most likely get yourself a mechanical 02 simulator and find an emissions shop thats to lazy to do a visual inspection. most places won't bother looking under the hood and crawling under the car unless its a new guy that does everything by the book in that case just play dumb you will still pass.
