cold air intake and exhaust

Which cold air intake is the best for the money?? Also, will cutting out my factory muffler be at all comparable to adding a 4" aftermarket straight pipe system? I don't have a converter so that's not an issue... Thanks in advance for any help.

The DIY 6637 intake is the best bang for the buck. Do a search for it for more info. As for the exhaust, straight factory exhaust will make a difference but 4" turbo back will make the most difference in EGT's.
