alright so ive got a little money to drop into my car and the modding bug has bit ever since i bought an injen intake
so heres what ive come up with

i could get a kinetix manifold (over a spacer because i want a different manifold when showing the car off)
samco hose kit
oil catch can an a stainless radiator overflow can
clear corners
new sparkplugs (43k on the origonals)
and a switch to synthetic motor oil and a better filter

or should i go with an exhuast
i was looking at the magnaflow because i can get it pretty cheap at my door and it has a stock look but deep sound

but i dunno how exhuasts sound on an auto

which route should i go? eventually ill have both but i want the best look and performance gains first
