Yozza too loud for track :(

[Schweppy]

Got noise tested at Castle Combe this weekend and achieved 103db! :S

The limit was 98db but i only have a 182 mani, sports cat and yozza sports system.

What can i do for track days?

Get a ktec stealth instead of the Yozza Big Bore 4

old rag up the exhaust FTW, and then once you nail it out onto the track it will blow out, job done

 

[Jay Payne]

Told you it would be too loud, you never listen to me

 

[Schweppy]

It was too loud with the decat but the new mani and cat makes it much quieter!

 

[Jay Payne]

Yea but its still too loud! Get a bigger middle box put in

 

[ForceIndia]

Don't get a ktec stealth on a ph1. Awful fit.

 

[Guppy]

tbh it didnt seem loud out on track compared to most of the other cars?!

 

[Fred@BTM]

static or drive by? just wop a supertrap or db insert up it

Static at 4500rpm.

Links? Dont know what they are? lol

 

[Fred@BTM]

static at 4500, bit low? christ! that doesn't sound right

 

[Greeny.]

It needs a foreskin, thats your problem.

 

[Russ_16v]

mine was 93 db with cat still in and a blueflame cat back, most cars were quiet on static and 300000000000000 times as loud when on track lol

Hmmmm it seems REALLY droney in the car too. Like i cant hear lol.

Hmmm WTF?

 

[W17GLE]

it was 112 db when my mate had the car my blueflame was a lot quieter. I was going to swap mine with the lad you bought the car off as mines only used on road.

 

[scalesy]

My Blue flame back box is a bit Loud for my liking had db insert in it when I got the Car I removed them and it went a lot louder so they do a good job any body want to swap for a quieter back box Lol!

FPMSL!!!

 

[sideways danny]

buy something less obnoxious

 

[richy22]

Just buy an insert?? I need to get mine db tested actually as I think mines rather loud

 

[Damo_Sport]

does this apply to 182 yozza exhausts too?

 

[Da]

Never had any probs with mine on track although I've never actually been tested.

 

[jamesp24]

Some home made baffles.

 

[Fred@BTM]

182 system was tested at 95

 

[jon_r]

Can you not repack it?

Supertrap? No thanks.

 

[Fred@BTM]

we use supertraps on the lambos at work just to get them through the static test, 2 bolts to get it off, job done

 

[KungFuSpaghetti]

sounds normal, Snetterton and Silverstone test static at 4500rpm, or at least they did last time I went. Pretty sure Donny do as well.

Link? What do i need for the yozza?

 

[Darren S]

I don't really understand the whole concept of noise ratings at circuits. Its a racing circuit, ffs - not a library.

D.

 

[Fred@BTM]

4500rpm isn't 3/4's rpm though?

i've seen allsorts to blag it through noise, baked bean tin is the most common!

Depends if they go by individual cars or take an average. I imagine they are clamping down on it a bit more as 82-89db is road legal, anymore is NOT road legal, so all the Yozzasport system are NOT road legal. Usually they will ask you what the max rpm is and then use 3/4 rpm as a rough guide, but I can see that changing.

Check this: http://news.bbc.co.uk/1/hi/england/8112905.stm

Most aftermarket systems wont be road legal, some will be no where near.

 

[Fred@BTM]

LOL love the F430 exhaust picture on that article!

 

[Craigus]

I'm surprised you failed it mate, some of those EK9's and Evo's were proper loud, wouldn't have thought they were quieter than yours?

 

[pug_92]

thought they came up around 95db. kinda pissed now as im expecting mine any day.

 

[Sym0n]

82-89db is road legal, anymore is NOT road legal, so all the Yozzasport system are NOT road legal.

When did this come in for cars? I know there's something in the MOT rules about testers discretion when it comes to the noise level an exhaust is giving off, but no limits as such.

 

[chrispy.clio]

My K-tec exhaust seems to get a little more quiet at 4000-4500 so when they ask me to rev it to that i knew i would be fine.
Mine was 96db (static) at bedford. but they said i was so so close to setting off the drive by sensors. (but i never did)

Won't work as at say Donington noise meters are round circuit.

1 black flag & warning .

2 black flags & it's home time

 

[Russ_16v]

Lol was a joke matey

Saw a chap do this at combe with an R33 GTR, managed one lap before being flagged

 

[Fred@BTM]

noise testing is a weird old thing, if the wind is blowing the wrong way you can pass, if its blowing the opposite way you can fail etc etc etc

 

[Englebert]

I'm surprised you failed it mate, some of those EK9's and Evo's were proper loud, wouldn't have thought they were quieter than yours?

Probably because they only rev it up to about 2,000rpm just like anyone else would

Stick your c**k up it Andy x
