96 Jetta Cat. Conv. part #

Hi
Well that pretty much asks it all...i wonder if anyone can tell me the Part # for the Cat. and if I need to one with the O2 sensor hole..Its for a 96 NOT California model gls 2.0..My car has very little power especially going up a small hill I have to floor it..The rpms dont increase either..It doesnt seem to have enough power to speed up enough at higher speeds to pass another car or even get off the entrance ramp for that matter...I really feel its the Cat...thanks for any help.....AJ.. Oh and the engine light is on...sometimes if i blow it out the light goes out.....But not this time....

Take a look at this cat for your car. It's cheaper than oem and should help you pick up some extra power.
