Hey guys i'm currently in the processing of trying to remove a yellow sticker and after being told that my exhaust is 6 times too loud they now want me to get a 5 gas exhaust analysis, which is to check if the catalytic converters are doing their job.
Does anyone know anywhere that i can get this test done? I have tried googling it but there is no info.

Thanks

6 x The Legal DB limit?!?!? Did they actually do any tests... that would be ~540DB (90DB being WA max if I remeber correctly)

yeh they did a test, when he told me i was kinda impressed haha but he said the DB scale is a ratio so like 40db isnt double as loud as 20db. i think he measured 103db.

Loudness volume doubling sound level change factor of perceived loudness formula calculate power level noise levels volume logarithm dependence three four fold loudness sound - by what factor does level decrease dependence comparison decibel levels 3

Roadbend Jaguar on Welshpool road will carry out an approved 5 gas analysis with a printout that the pits will accept. Don't expect your car to pass easily though.

oh cool i'll check them out. the catalytic converter on the exhaust at the moment is hollow apparently but it's getting an ultrex tbe put on so i'm hoping that will pass because it has the 2 cats.

Lol. Learn some physics

Sorry I am not a physics nerd Instead I decided to get a degree in life.
