Scorpion exhaust fitting

Hi all,

Jut bought a scorpion non resonated for my 197 and will be fitting tomorrow.

It says in the fitting instructions to cut out a 70mm section from just behind the lambda nut.

Is that something that needs to be done or is that just there in case it needs some adjustment?

Cheers.
 
No, take that as gospel in my opinion as it's to make sure the system then fits correctly all the way to the exhaust hangers.
When mine was done, my mate double and probably triple checked the measurement, and he's a Tech by trade...

Thanks. Just what I wanted to know!
