Westy Posted February 17, 2012 Share Posted February 17, 2012 Usually the second cat is required for a TT to pass the emissions test mate. I'm sure the single guys must know a friendly tester as an MOT goes on the engine model number for this test!? Link to comment Share on other sites More sharing options...
caseys Posted February 17, 2012 Share Posted February 17, 2012 it will pass with out the cats Unless you've got it running engine-threateningly lean... pull the other one. Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted February 17, 2012 Share Posted February 17, 2012 anyone got a definitive answer on this? will the 2nd cat be enough on a single? Link to comment Share on other sites More sharing options...
Noz Posted February 17, 2012 Share Posted February 17, 2012 I've heard some engines pass, and some don't. Some NA without cat's dont pass. Link to comment Share on other sites More sharing options...
caseys Posted February 17, 2012 Share Posted February 17, 2012 anyone got a definitive answer on this? will the 2nd cat be enough on a single? When i can I'll take mine down to my MOT centre and get some readouts of emissions via all the maps, may help. I think as Noz said, condition of engine too counts.

bigbloodyturbo Posted February 17, 2012 Share Posted February 17, 2012 I have a friendly mot tester lined up but I don't know if he's going to go as far as bodging my emissions if they're really bad, he told me they have started really cracking down on this stuff Link to comment Share on other sites More sharing options...

jawan Posted February 17, 2012 Author Share Posted February 17, 2012 lets say If I need to put cat on how do I do that on a single supra? Link to comment Share on other sites More sharing options...
Bailey. Posted February 17, 2012 Share Posted February 17, 2012 Just remove your mid pipe and fit the second cat, as above, most have a friendly tester. Link to comment Share on other sites More sharing options...
D8MOA Posted February 17, 2012 Share Posted February 17, 2012 well my glanza passed with a decat so surly a supra will?? clearly a 1.3 4 cylinder and a 3.0l 6 cylinder put out the same emissions so both will pass decat'd Link to comment Share on other sites More sharing options...
bignum Posted February 17, 2012 Share Posted February 17, 2012 Depending what downpipe you have( most are v band) with single kits, you`ll need to adapt the cat to fit, i`d say it won`t pass emissions without a cat. Link to comment Share on other sites More sharing options...

Ian C Posted February 18, 2012 Share Posted February 18, 2012 A TT will pass with only the centre section Cat fitted, and it's relatively easy to fit compared to the downpipe one Link to comment Share on other sites More sharing options...
