So, just had my catalytic converter stolen from my rx400h 2008 a few days ago, and I am looking into purchasing the converter my self as mechanics charge up to £500 for the job when the catalytic can cost as little as £100.

Here are a list of converters which I found that fit the RX's

1. Magnaflow 200 Zeller Metal Sport Catalytic Converter Lexus Rx 2 1/8in
2. Magnaflow 400 Zeller Ceramic Catalytic Converter Lexus Rx 2 3/4in
3. UNIVERSAL T304 STAINLESS SPORTS CAT CATALYTIC CONVERTER 3 INCH 300 CELL-LXS
4. Lexus RX400h High Flow Cat MAGNUM Performance Catalytic Converter - Vehicle Specific - Universal Installation
5. MagnaFlow 23624-AF Fits 2006 2007 2008 Lexus RX400h Catalytic Converter

Are there any more converters out there?

Also, what are the specs on the original lexus catalytic converter?

And do we want metal or ceramic, higher/lower CPSI? the higher the cpsi the lower the emissions, the lower cpsi the better performance apparently? and metal seems to last longer also? someone please advice.

 

Hi, do we know whats the diameter of the exchauxt pipe on the original part?, below are the diameters of the magnaflow catalytics, i need to know which diameter to choose which matches the original exhaust pipe or at least get an exhaust sleeve/adaptor/connector

1. Connection diameter: 54 mm / 2 inches
2. Connection diameter: 60 mm / 2,25
3. Connection diameter: 70 mm / 2,756
4. Connection diameter: 60 mm / 2,3
5. Connection diameter: 48 mm / 1,75
