How loud?
 

How loud would a muffler delete be without any cats? Are hi-flow cats restrictive at all? My plan is F/I at some point. If Hi-flow cats are not that restrictive, how loud would it be with catless headers but catted mid-pipe?

I really like the sound of all these muffler deletes but it seems everyone that has done one is on an otherwise stock exhaust system. The exception of course is Crawford, but they are running a turbo which I'm sure quiets it down.

Thoughts?
