My friend has a Dynomax VT muffler and it sounds nice and throaty. No drone and only loud at WOT. I know this muffler is made of stainless steel so it won't rust easily unlike the Dynomax Super Turbo that is just aluminized.
I have the Airaid and it sounds ok. Bought one because of the deal I got from 4wo|cold air intakes before. Aside from Roush and K&N, BBK and Steeda are good intakes also.
Powdercoating the calipers is also a good method, though it will take more time from doing complete removal to putting them back and bleeding the brakes.
I also have a covercraft sunshade without the logo. It works great. What I like about it is its stiff material compared to inexpensive ones that has a tendency to sag faster.
What he said. Currently have BFG g-Force Sport Comp-2 as my summer tires. Got them from 4wheelonline|click here for tires. Very good traction and handling. I like how they stick in the rain. There's road noise but not really annoying.
