Hey everyone

My Mercedes C240 Elegance 2001 model never had it's Catalytic Converter replaced. And I'm thinking of permanently removing it.

I need everyones expertise and opinion on this.
Is this a good idea?
Will the car be more fuel efficient and have more performance?

Can one imagine how dirty it must be 14 years later?

currently car is just swallowing petrol like it's no ones business. one tank(62 lt) lasts me 5 days exactly. I drive normally and 110km a day. from a 62lt tank i can do about 480 - 520 km.

Much Appreciated

 

I have a CDI.

Last year my converter clogged up and the dealer removed everything from the inside and refitted the exhaust. No problems but the turbo is whining very clearly now without the converter. I was quoted $2200 for a new one.

Also no problems with the yearly inspection. Though diesels will pass the emission tests without the converter unlike petrol versions. This depends on where you live of course

 

There shouldn't be a decrease in performance - and a very slight increase in performance due to less back pressure. Be careful though - depending on where you live, even if you don't have to go through emissions testing now, you may need to in the very near future.
