thanks guys for your replies..
eg_project i plan on getting h&r 2 inch lowering springs first, then followed by a universal muffler (the reason im not getting an exhaust system is because even the apexi n1 exhaust system only boosts hp by 1.3 and thats not worth 599 dollars
) and then i get my sound system installed, along with shiftknob and light bulbs :-D
