				Hi my phase 2 172 has had some headwork/cams done and running on an Oreca group n exhaust with sports cat. 
It was custom mapped with these mods present. Before I got it.
The Oreca i fear is going to be too loud or at least borderline on drive bys on track so have bought a ktech stealth twin box system.
Is this likely to make any difference to performance or give any running problems?
Cheers
Dave
