The cheap intakes just make you injest 200 degree air killing performance. Like said, stick with K&N or another good brand that has heat shielding.

Those "chips" are junk too. Either get a modified PCM or find a local dyno tuner and they can do wonders for you. Of course do this after all your mods.

You can legally change exhaust after the catalytic converter with no warranty issues. I had the dealer swap my cat back system from my 2001 to my brand new 2004 as part of my sale.

Slap a set of magnaflow or dynomax ultra flow mufflers on that V8 and let it sing.
