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.

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.

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.

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

billyboysm3 · 20-02-2012, 12:27 PM
