Here is what you want. "Trust me on this"

Get polyurethane bushings for the rear
Get an 03 cobra pinionbrace.

Then drop a k&n filter in the stock air box and buy the FR 500 cat back. It adds 10 HP at the wheels and cost $650.00

Then throw in some 4.30 gears and even the 03' cobra will eat your dust.

I have thoroughly researched this subject,

Oh yeah leave the air silencer in there my car ran slower without it.
