350 mag qusetions
 

I have a 23' v hull cougar with a 350 mag injected. It came with a 21p rh ss vengeance on it. It will run about 60 - 64 with 3 people in it. I want to add different exhaust manifold (EMI Thunder or Hi Flow type) and a different Air filter type, and was wondering what others ideas are on what is the best prop (4 or 3 blade and pitch) Also opinions on exhaust replacement.

Trying not to break the bank either. I know you can go crazy just want to make it a little more power with out losing the turn key reliability.

thanks for any input.

you will lose a few mph with 4 blade prop but it will handle much better
