BEST HFC or catalytic converter for G35 sedan?
 

Hy to everybody.
I am forced to replace my cats on 06' G35 6MT!
What are the best options?
I am looking for cat.conv. with moderate sound over OEM?
What you think of Magnaflow direkt fit cat. conv?
Is magnaflow flowing better than OEM or not, has anyone actually tried Bosal?
Performance is not the main issue, I just need decent daily driving cat.conv. that does not smell on exch. gases if you push it!
