Noisy supersprint track days

[shimmy]

Ah... Ive heard of this place
They do the famous "cook your meat" on the hot stone thing

That's the one, you just flop it on the hot stone and everybody takes a bite!

Right then Gav.

Got db tested yesterday.

System now SS Cats, yes they do have cells left in them, standard centre pipe and SS lightweight race still pumping out 107 db when hot.

I pass driveby.

Has anyone got a standard back box i can borrow for a couple of weeks, to fit and work out if its my SS Lightweight that is very very loooooouuuuuuddddddd.

The Standard centre pipe definitely makes the car quieter.

[gav]

Ok, that's good to know, thanks Billy.

Waiting on a price for oem centre tomorrow. Was (maybe) going for ss silenced centre section, more likely standard.

Hmmmm, if its not made a huge difference to you then i may rethink.

Maybe the wadding gone in yours or something?

Most places ive read say folk with ss lightweight/ standard centre or ss centre silenced fine on track.

What about leaving alone and trying a clip on track day silencer if needs

The cats make it loud Billy.

Go back to standard, I doubt they will make any noticeable difference.

Im putting standard cats on this week before TD on Sunday.

I have got clip on silencers but Ill figure out first if its the cats or back box.

Lawsy do you mean the approx 5 bhp?

[shane@mbtech]

Who told you it was that much. I reckon 3 with a drop in torque

Don't use super traps! Danger of killing the engine.

[DuncanR]

Billy, I may have a back box still tucked away up in the loft, will look later if you still need to borrow.

[billyboysm3]

Nice one, Ill do cats first and then see.

[billyboysm3]

Cats changed, car is quieter :bigcry:

Lets see if I pass Snetterton DB test on Sunday.

Im guessing 102db

[gav]

Good luck Billy.

Sourced a csl centre section, on its way.
Will prob take a couple of weeks before fitted.

[billyboysm3]

Gav, I got 105db on static, but that was after the car was sitting for 40min.

I reckon hot id get 102/103db.

Thats with Standard Cats and centre pipe and supersprint lightweight race back box

[gav]

Ok.

You keeping it that way or doing anything else now or are you happy with that?

Ill hopefully change next week

Was going to maybe get tested at knochill on sunday but cant do that now.
( not that you get grief there)

[billyboysm3]

Im keeping it like this. Your back box might just be like mine and runs super looooouuud.

Changing the centre pipe will save you about 2-3db.

But I would get it DB tested first at your local track when warm and then after when CSL centre pipe fitted.
