the gp has over 164k on it just isn't getting the fuel mileage that it once did. when i did the tune-up around 100k, it just didn't seem to help as much. i've read where people have changed out their cat and it made a huge difference in power or fuel mileage and that is what i'm looking for!

i asking if there are any recommendations on where to buy one to replace it. i am not really sure if i need to spend a lot of money a bigger pipe since the car has so many miles on it and don't plan on modding it. if it isn't that much more, then maybe it would be worth it.

it would be nice to get one with out the u-bend already. i went to the local muffler shop and had it taken out 2-3 years ago, but the guy didn't do it right and it would scrap sometimes and then o2 sensor went out.

anyways, if there are any places that you can point me to on getting me a replacement would be great. i know there are many of you that have looked at them so i hope that your input can help me.

i just put in catalytic converter on google and some place came up and the prices were not that bad for the whole thing, but it did have the u-bend.

i would like to have a good high flowing cat though and i'm not sure if all of them are this way or just certain ones.

thanks for any help :rolleyes:
