Re: 2004 going to Cali
I would replace the straight pipe when possible. Hopefully you kept the muffler and it's a quick fix.
Kawlifornia looks down on that type of stuff rather harshly. Can't even put an after market air intake on a crossfire unless it has the California Air Resources Board stamp of approval and none of them do..........
I brought a crossfire into to cali from texas in may. What a PITA. Smog check, visual check and then 20 minute inspection at the DMV to verify VIN #'s and that all the emmissions stickers were still under the hood. The wife sure loves her car so I guess it was all worth it.
