davidii and kingseth2, thanks man, yea, for 6th generation i just found out it was 8 years or 80,000 miles u can get honda to pay for many of the emissions things, like the 3 way cat, one problem, they dont pay for it, if they feel like i tampered or didnt properly take care of the car. i have an exhuast and CAI, so i think, I KNOW their gonna blame the problem on that, cuz i went there a few times when i still had my warranty. so kingseth2, when u got honda to replace urs, did u have any aftermarket stuff? so the real question is this guys: should i just take off my exhuast and rebuy a stock one(like ive seen them for $100-200) and put that on, and put on stock air filter and get the cat done? or should i just go straight ahead and buy a new hi flow cat from carsound? thats like $80-150 also. will i pass emissions tests guys with a high flow cat?
