yes, your check engine light will go on and you wont be able to pass emissions. nothing performance wise will be effected though. run a cat. it makes the exhaust less crappy sounding, doesnt get the rear bumper all dirty, and saves the world (if youre into that sort of thing).

no need to go catless as it is not a restriction. if you think that deleting the cat and resonator and adding in flowmasters is going to sound good then i have bad news for you. it will sound mega crappy. you like ricer rasp? you got it. keep the cat, keep the resonator, and replace JUST the mufflers. get a 3" downpipe WITH a cat and bolt that in there. im already telling you that if you do what you described that youre going to regret it unless you like loud ugly v6 sound. these cars are meant to be quick and quiet, not loud and obnoxious. leave that to the hondas that think they get more power from running a straight exhaust on a 4 cylinder that makes less power than my lawn mower.

Welcome aboard Jaime! I hope you've checked out the local board Kansas City Pontiac Motorsports Club

Bio...is a cat lover - I don't mean feline. You'll get differing opinions on the restricion of the stock cat - personally, I would remove it and either go with a hi-flow version, or none at all. He did however answer the rest of the questions correctly.
