if it's just a muffler it wont do anything besides make it kind of obnoxious and make your car look rice-tastic

you should stop and read! you are clearly not ready to change a valve cover gasket let alone an entire engine. you have a lot to learn, but that's ok we all start somewhere. read through the faqs here and honda-tech as well. lots of good info to be had. I would just stick with the motor you have now and work with it. do a dpfi to mpfi swap, and then maybe a mini-me swap. you can google search both of those things and find lots of info on them. you may also want to switch to an si transmission with shorter gearing. once you've got your hands dirty a bit then maybe consider swapping to a whole nother engine platform. my 2 cents anyway
