i was lookin for some input..

sooo i was thinkin about gettin some mods that are less noticeable, expecially when a cop decides to POP my hood. i want some power mods that they wont know what it is when they see it.. unless they knew anything about cars

so far my list is.
cobb lightwieght pulley
cobb up pipe and down pipe
---
any other suggestions? or better brands?
and if i change those how much does( if i even need) - Tuning cost?

oh yeah. keeping it under 1grand also.

short story for this precaution

i was driving home and 3 cops in 1 police car pulled me over, they initially pulled me over for a AFTERMARKET EXHAUST, while i explained to them that it was STOCK.. since it is. I got punked, they told me to shut up-- and all sorts of other things that showed they were just really gay people who had nothing better to do. they explained that my AREA was complainin about LOUD exhaust and so forth.. anyway. i got cited for Runnin a stop sign -- which... I DIDNT .. and not having a front licenses plate. its funny that they would catch and cite me.. when every day and night people do donuts infront of my house... and never get caught-

anyway.. soo any inputs anybody?? not about my situation but.. the mods

thanks
