Remove air silencer--free
K&N panel filter (not the FIPK)--$40
Catback--$200 for the dynomax
Other than that, all my experience is with the 4.6, but there's a ton of stuff out there for the 5.0.
i agree, with the exception that the pullies should be pulley...not plural. the kit includes an alternator pulley which is useless. i bought just the ASP crank pulley from summit for like $75. you might want to spend the $200 on a custom exhaust. i had the dynomax, and was disappointed...especially in the sound dept. couldn't hear anything. to each his own.
