Performance 7afe, Want some more horses Options

[Hawkins Corp]

I am currently on a search for a newer 7afe and before i put it in my DAILYDRIVER i was wondering whats the best way to get a little more out of it without supercharge or turbo i am on a budget of about 400 dollars and i would like to just force a little out of it. Im gunna do the swap myself and i just want to do everything to it b4 i do the swap so any feed back at all would be great. Oh and its an automatic.

I honestly dont know where to even start with this project but like i said just squeeze some more out of it besides the intake and exaust. I am gunna have a frind make a full exaust for me and i was thinkin about a 2.5 inch to much or not?

Thanks,
Brad
