Just search DMH cut outs on google.

I have no dyno to prove it but a catback gives you like 20 hp, about 15 wheel. Cut outs make more power than closed exhaust so I think it probably makes almost 18-20 more wheel when they are open.

BUT I have no dyno to prove this yet, someday Ill get one.

You would at least get as much as a catback though.
