Well lads..
Just joined there today .My altezza Failed on exhaust noise levels yesterday its a cat back system dunno what make..
Ordered a silencer there today .. will it pass with a Silencer in the Backbox??
The also failed it on Emissions but i think its due to the fact the engine was cold when the tested it..car was parked at test centre for about 4hrs before testing..
Any Help Appreciated:)
How did they measure the exhaust note? from differant angles etc?? just stuff lots of wire wool down it, think thats what ill do if i have to.
As for emissions, the car needs to be at running temp, question that.
Also, moved to the right section
Theres about 3 million factors to be declared before we can answer this question!
Its not simply clear cut
Obvious question but is there a cat in the car? Unusual for an Altezza to be over 99db with just a cat back?
Going to try it with the wire woll in the Exhaust aswell as the silencer baffle in the backbox..
I dunno which way the tested the noise levels man..i left the car in the test centre at 8am before work and the test was at 11.50am so i persume teh car was cold when the tested it
Running oil temp will be on your fail sheet ;)Quote:
