New guy here and future owner of 04 Grand Prix GTP. I haven't picked it up yet but its at a family members house and hopefully in the next 3-4 weeks it will be mine. It needs new spark plugs,catalytic converter, and has close to 200K on it but I'm also picking it up for scrap price which I consider a great deal. Just couldn't see it going to the scrap yard. Now for a few questions.
1) Is there anything particular to this year that I need to look out for?
2) Is there a recommended brand of spark plugs to run in these?
3) I just plan on getting a ZZP 3" downpipe with cat. Is this the best course to go when it comes to the catalytic converter/exhaust or should I look into something else?
