Gav, so you have standard cats, SS centre Pipe and lightweight race and failing static 105db test?

I have SS headers , SS metallic cats , SS resonated center pipe and race backbox (not lightweight) .
And my car is around 95 DB .

Basically Billy that is right.
Havent personally looked at centre section as cant get that far under.
But mechanic say... Standard cats, larger bore centre section that supersprint on it. So presume that is right
Defo has lightweight racing back box.

I havent failed any noise tests, but have got grief and raised eybrows from them nearly every time at croft and oulton. Got sent away last time, but after pleading etc.

Just dont want to be prevented from going on at any point if i can prevent it.
Particulatly if there is a straightforward solution.

Once was defo due to poor revving technique at testing... Pops etc being quite noisy.

I am intrigued to see what db my GTR will be kicking out, its not too loud when stationary, but being a turbo the noise under load increases more so than N/A.

Hope I dont get kicked off.

Standard cats, SS resonated centre section and SS lightweight race backbox is good for all TD's, takes away rasp (which I really like) and sounds good.
