Iv got a mongoose exhaust on my 3dr with only a back box, I got a letter in the post saying my cars excessively noisy so I have to get it tested, Does anyone have any idea hat DB reading it will get? Its a 450hp engine, K&N induction, T38 Turbo ,100 cell cat

Iv driven the car a whole 24 miles and got a letter already

The legal limit is 90DB but they also check the sound when the engine is de-accelerating

 

if you've got an I-fone theres an app you can get

 

i dont think the apps going to be as accurate as there equipment I just need to see how far off Im going to be as I can fit a diffrent cat if its going to be a few DB iv got a 100 cell on atm and can chane it to a 400 cell one

 

iv jut come across an apexi butterfly exhaust control valve which might work or atleast it will help for any future problems I may have

 

Is this in the Uk or Aus?

 

My old single box mongoose used to produce 95 decibels according to castle combe noise testers ..

 

90db is very very quiet!!
tabetha

 

Why do you have a cat on it out of interest?

 

In oz.. I have to have one over here mate

 

thats a bummer having to have a cat

 

at idle ?

 

Not to bad being a 100 cell

 

Get another box in it Aaron

 

i will do mate, il be taking it to the exhausts shop in a week or so and geting him to test it to see where its at now and then make the changes

 

There is no such legal limit, that's balls.

There isnt any government approved test equipment, there isnt any limit, there isnt any test procedures laid out.

Who exactly is the letter from ?

 

stevie he's in australia not the UK.

on the cat side did aussies introduce cats massively early compared to rest of world or have you been bum raped because its an import car??

 

not in britain but he is in oz so maybe its different there?

 

No idea then lol

Sounds like he maybe has neighbours that need burnt out or something.


A friend recently moved to Oz and took his 2003 STI with him. It didnt have a cat fitted, and he had no problems registering it and getting it passed for the road ?

 

Depending on where your mate lives if e gets pulled with no cat its a 10grand fine.

My neighbour has a mustang

Its police that reported it to the EPA

 

Weird...he had no problems whatsoever getting it road legal and registered over there

And what a ridiculous fine over nothing. CAT's serve little useful purpose in the first place !

 

theres no issue geting them registered as long as you have a valid roadworthy (MOT) and you can get these easily through dodgy garages etc The issue is when Vicroads (dvla) or the police pul you over and check over the car and give you a canary or worst i EPA give you notice to have a full check over the car thats when your screwed thats why im lucky it was only a noise test

 

Aaron, I've been using 'Daalder Exhaust' and I've seen them with the sound test equipment out on cars ... so they'll know the details required.

I can vouch for the one near me ... although there is one in Dandynong, but I haven't been to that one.

I got pulled over once by the police cause 'your engine revs noisy', but I have a Scorpian system on and its quiet at idle. A quick look at the car and check my licence and I was on my way with no issues.

You know what annoys me ... Harley Davidson noise levels ... yet they get hung up on cars.

 

Harleys are delivered to australia with pee shooter exhausts mate and get swaped over at the shop thats how they pass adrs.

Yh mines not really that noisey imo theres v8s with a hell of alot more noise.. It was more down to the fact the exhaust was blowing out smoke due to the turbo.. Il be going to the same place but in dandenong mate.. How are the guys down by you?

 

After getting messed about and blown off several times from Performance Exhaust at Airport West ... Daalder were v helpful. I dealt with Dwayne, who even after the suppliers lost my order kept me in the loop and completed the job on time when he could.

I test the water with my other car ... so yes, I'd be happy taking the Cos there for work now.

On the TX3 Turbo they changed my stainless straight through with a stainless baffled one, as I was trying to quieten it down. Installed with a flanged fitting and modified my straight through with flanges so I can bolt it back on when I want ... they were happy to do what I requested.



One time I was there they had the sound measuring equipment on a VE SS doing testing ... so they should be able to sort it.

Hopefully Dandy will be just as helpful.

If you were seen blowing smoke ... your not up for an emmisions test are you?

 

No mate they let the emissons one go lucky.

My mate down in ftg can do all the exhaust etc so it has flanges for quick bolt and release etc so il be getting him to do that

Just gota get the car running again now

how was SFS?

 

Aaron my escos does not have a CAT either. Never had one from when they changed the exhaust back in 1993.

 

im not 100% sure if the rules are diff there mate

 

If they are mate i will get one fitted like yours, one that i can remove if needed.
