i got a question.. the setup goes as this right... short h pipe connects to long tube headers, then the midpipes connect from the h pipe.. then the mufflers connect from the midpipes, then the tips?? is that the proper setup?

 

headers to h pipe to mids to tails

 

Your mid-pipe is the h pipe so it goes like this,Headers,mid-pipe[h or x pipe],flow tubes,mufflers,tail pipes.
