EXHAUST NOISE

[kingersman]

Okay so the previous said he got the exhaust tested and everything.

He said it was testing in between 93 and 95...

Just wondering say if it tested just over 95 but not by much would that have to be a instant fail on a WOF or would they give leway?

Think you will find if it is a whisker over 95 you will get a big fat fail. You might get some lenience if it is a competition car (rally/track etc) that is obviously not going to be driven much on the road. But if it's a "street" vehicle I would imagine most testers will be pretty strict.

Although there are things you could do. You could check out the actual testing procedures and make sure the tester is following them properly (there is a percentage of redline, distance from walls etc). Other than that just put another resonator in there to take it down a couple of notches.

Just be happy all the recommendations haven't been implemented (yet). A car caught exceeding the 95 limit would from then on have to meet 90.

Well I went for my WOF at my usual guy who passed me 6 month ago and he said to me as soon as I rolled up that cos my exhaust is modified he wont pass me based on that. I thought it's a load of crap really. Visited a couple of exhaust shops and one of the guy tested me with a handheld db meter and it reads 92-94 db and he suggested me to get an objective testing done. If mine passes the test does it means that I wont have any more issue like this providing I keep my exhaust the same and condition? This whole exhaust noise thing seems to me to be applied inconstantly and only pin the good guys. It's gonna cost me 225 to have my exhaust noise objectively tested and possibly more to modify it further on a system that was installed more than 3 years now and had no problems with the cops neighbors etc. Pissed! I've got a 96 wrx with a 2.5 inch Siamese pipe to a 3 once with one resonator and a muffler.

They all seem to be cracking down on modified (in any way) exhausts and I've noticed alot of WOF guys won't go near them. If you have a noise certification it will pass that part of the WOF test without issues.

So i suppose if i want to keep my sports exhaust i have to spend the money. I suppose it's gonna cost money to go back to standard exhaust. BTW i have downloand a DB testing application from my iphone and will try that out to see if it works.
