I have a 98 Protege, 1.5L, manual transmission.
I need to replace both the front and rear converters, as well as O2 sensors.
Which brand of converter is recommended from e-catalytic? I'm looking for direct fit, do they come with gaskets or are these separate?
I also noticed O2 sensors from NTK, Bosch, Denso, is anyone better/preferred than the other?

Thanks for the help, great forum!

 

Might as well replace the downpipe and muffler as well, Bosal makes some good stuff. I have had luck with NTK sensors, but you may not have to replace them. When you buy the exhaust, don't forget to get the gaskets too.

 

Thanks! What about Catco or Eastern converters?

 

either are good
