smijay Posted June 15, 2017 Share Posted June 15, 2017 Hi guys, had my 350 in for its MOT yesterday... all fine apart from it failed on the lambda test reading. The mechanic said that he tested for 15 minutes straight and the lambda reading was just fluctuating everywhere. Upon investigation I've found that the flexi on the passenger side of the cobra Y pipe looks like its been scraping on speed bumps and is basically shot and leaking exhaust gasses. Has anyone else had problems like this? And has anyone got any ideas how I can stop this from happening again? The only thing that comes to mind is mount some kind of metal plate over the flexi to stop bumps hammering it! Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Jake.Lowther Posted June 15, 2017 Share Posted June 15, 2017 Haven't had this issue but in certain I've seen some braces for the exhaust you can buy which lift it up a bit protecting it from hitting the ground, might be worth investing in if you're going to have to get another y pipe.

smijay Posted June 15, 2017 Author Share Posted June 15, 2017 Got the guy to chop off the old flexi and weld on a new one and it flew through emissions with no problems Good suggestion though i'll have a look for these braces you speak of!
