My mechanic says my catalytic converter on my 2000 Nissan Maxima SE is shot. He works at a Nissan shop and said the part/labor is over $1K. My question is, how important is this part and could I replace it with a used part (since the car is almost 10 year)? Suggestions?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Jackson, Unfortunately, a catalytic converter is not made to serve forever. Soon, it will get damaged and the best solution is to have it replaced with a new one. If it is already defective, overextending its usage is an unwise thing to do because it may cause your engine to emit a large amount of harmful gases, thus compromising your vehicle

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube The catalytic converter is part of the emissions system. Do not remove it and forget about a used one. Check with a non-dealer exhaust repair shop for a comparison quote. Failure to correct this may also cause your car to run poorly.

Laurie Sarno, Co-Owner at Super Girls Auto Hello Jackson- EPA regulations forbid the sale & or installation of used catalytic converters - many muffler shops install new ones at 1/2 the price or less than the dealer- the part is important if you have emission inspection in your area as your car will fail the test if the converter is bad or is removed- thanks Super Girls Auto.

Pat Fleischmann, Director of First Impressions at Community Tire Pros & Auto Repair Well..Your nose must be smelling "rotten Eggs!" This is the smell you get when your catalytic Converter goes out...This is a vital part of your emission system and keeping the environment clean! No used part here..when they go~ they need replaced! This car is ten years old, sounds like it*s a trusted vehicle and this is just one of those vehicle/parts that needs your attention, after all you*ve got your monies worth out of it! The fix is cheaper than purchasing a new car or a used car with unforseen problems! Buying a part outside the facility is really touchy, as they may not warranty the part~ They*ll charge you to put it in, but NOT cover it! I*ll attach a link, but you*ll have to have a dialog with your facility whether you want to go this direction...I don*t advise it~~ but wanted to give you an option for your purse. Shortcuts may cost you in the long run...Time to Pay & get it FIXED right from an ASKPATTY.COM facilty in your area! Pat Fleischmann
