GT_86 12 Report post Posted November 16, 2019 Today was my first MOT since having the UEL Manifold and Cat Back fitted. It passed but initially failed on the first couple of emissions tests. Tried it in all maps and it was in map 4 when it passed. I did take advice from reading on here and it was well warmed when I turned up for the MOT, but the emissions test was last so it may have cooled down a bit before the test. Either way it passed it the end. The tester mentioned the MOT rules were changing next year and any exhaust sounding louder than factory will fail! He told me that is not just starting from a particular model year and will apply to all! Anyone else heard of this rule change coming in next year? . Share this post Link to post Share on other sites

Xyra 8 Report post Posted November 17, 2019 I don't know if it's getting stricter next year, but currently I believe the mot rules say it can fail if the car is noisier than a similar car with stock exhaust. A quick hunt on Google says this came in around 2010ish and people often get advisaries but not been able to find anyone failing with it. Use a garage that understands performance cars. "yes sir, this car is a sports car, a similar car car with stock exhaust you say? Well this Pagani is also a sports car, let's compare exhaust volume" 1 Angelina reacted to this Share this post Link to post Share on other sites

nerdstrike 186 Report post Posted November 17, 2019 Wow, some the testing regime for new cars is done under full power! Those are some tough regs. I guess that means aftermarket exhausts will need extensive testing. Sounds expensive. Share this post Link to post Share on other sites

nerdstrike 186 Report post Posted November 17, 2019 The regulation document specifically stated full power at the highest revs available for that power, i.e. 6500 rpm on the GT86, but that might be quite a way from redline on small turbo cars. It's stated that way to accommodate hybrids and such I think. Share this post Link to post Share on other sites

"Exhaust noise from the vehicle must not be unreasonably above the noise level normally expected from a similar vehicle with a standard silencer in average condition." It is down to the testers discretion so just take it to your local friendly MOT centre, there's plenty of partially deaf testers around 😉 1 Deacon reacted to this Share this post Link to post Share on other sites
nerdstrike 186 Report post Posted November 21, 2019 It's true that there are already some poorly observed rules about exhaust volume, but the new regs will drop the noise ceiling which in turn may need additional pressure to enforce. We'll see. Share this post Link to post Share on other sites
