Cats changed, car is quieter

Im guessing 102db

Good luck Billy.

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

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

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)

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.

Sounds like a good idea...

I (may) invest in a set of bolt on silencers in case.

Got tested at croft a few weeks ago.

About 99

Happy with that.

I fitted a csl centre section. Brought it down a wee bit.
Still fecking noisy... But good.

Maybe i get a csl back box

Ive been thinking about changing my milltek back box little bored of it now just wondering if anyone has run milltek race cat and centre pipe with a lightweight supersprint race back box and had a db test? or any sound vids with this set up cant find anything in search.
