Cut outs...I would like to hear pros and cons.

Well.......I said that and I think about it and there is ONE way I think I might like them and NOBODY ever does it like this. If they were installed RIGHT at the header collector, they would probably sound badass. But people always install them further back and the sound from open headers gets lost somehow.
I will certainly think abt doing that if I decide to do cut outs.
Thanks Rusty.
