Anyone have any luck with performance fuel injectors if there are any out there and had any performance from larger catalytic converters? 2005 model so the o2 sensors are before the cats and I just hit 155555 miles :) and was thinking to change the fuel injectors to a performance set, which I really have not found let alone whether its necessary to change them, both for that matter. If you don't think its necessary tell me but if you have done it and seen any changes in performance let me know.
 
Stock is fine if you have done nothing else to engine.

Stock cats from all makes and models are very good at flowing exhaust for car they are on...
 
thanks man, well then I will leave them alone for the time being. Anyone have any info or something for me on the fuel injectors?
Hey like ygmn asked have you done anything else with the Engine? The factory fuel injectors are more than capable at stock power levels. But keep in mind any change in flow rate would require a retune in the pcm. Otherwise money would be better spent on a cam n springs. 😀

If you need more fuel I recommend going with a nice set of fast or just bumping to the 8.1 injectors on the cheaper side.
