What can I do to my V4 F23A1 01 Accord to make it sound great?
 

I just got a used Accord with 150k miles on it, this is my first time actually modding a car and I want this car to sound really nice. Any suggestions on air intake and exhaust systems I should get? Is there anything else I can do to make it really stand out? I really don't know much about cars in general so any tips about general things would also be really appreciated.

welcome to the forum. You can google, utube, and it will show you how to do it. cat back mufflers are nice, aim intake is good or k&n
intake, dyna flow are mellow. couple of points of interest, if you are a young teen, the police will be looking out for teens in Hondas. use honda only fluids, and any sensors get from the dealership. after markets look the same, Honda has theirs done for Honda only. if you are smog restricted, change back to stock cat for inspection then change back to clear cat.
