Making my own custom exhaust?

Is there anyway someone could give me some instructions on how to create my own custom exhaust for my 1994 prelude si? i really need some cheap quick way to get come horse power and i was wondering if i could do this myself. i have a new muffler and i just need to know what i need and how to do it. thanks boyz ill really like to hear your thoughts and help!!!

you can put a straight pipe or gut out your cat.

i would take the muffler to a muffler shop if its not a bolt on

what kind of pipe would i use? i mean, how would i get it to bolt on to the cat, and all that stuff im just so confused and feel like a dumbass

Save yourself the headache and buy a Pacesetter catback and cut off the the muffler that comes with that cat back. then you can weld your muffler on. Pacesetter is cheap in price. I had to buy Pacsetter because it was the only thing available for my 88. Then added my own exhaust.
