dssnosher Posted March 11, 2010 Share Posted March 11, 2010 Checked my car at mechanic and he said that catalytic converter isn't performing the way it should be. Its a 98 GS400 with 270,000km on it. What can happen if i keep driving without replacing the converter? In case i need to replace it, would aftermarket one work fine? Quote Link to comment Share on other sites More sharing options...
drew028 Posted March 16, 2010 Share Posted March 16, 2010 my engine light comes and goes for my cats. Dirty cats can take away from the cars performance depending on how bad. It can also effect your o2 sensors in the long run. Id replace them with the factory ones. Cost more but less work and no welds to rust. Cheapest direct fit i found was here http://www.car-stuff.com/mmparts/lexus-gs4..._converter.html. If anyone know where to get a better price please post.

drew028 Posted March 20, 2010 Share Posted March 20, 2010 ALSO, your old cats are worth money. When i do mines i got a guy to give me 120 each.. $160 each new that will the cut the cost way down and make it affordable. Quote Link to comment Share on other sites More sharing options...
