Just bought a 2003 silver Z for myself and a 2004 white Z for my wife. We love them! What is the first mod that I should look into? I'm about to get my stereo stuff put in, was thinking about exhaust next. I am looking into getting a TT put on in a year, so I need to prep the car in the meantime.

 

wow couple car welcome

 

welcome!!
congrats on the new purchases!!
A good cheap mod while your waiting for the TT (IMO) is the JWT Popcharger. Airfilter and heatshield. You can find them used in the market section for $60-$80. Also, unorthodox racing pulleys are a good mod too.
Gets some pics up of the new cars!!

 

Congrats to the both of you, and welcome!
