does anyone have an opinion on what are the best headers to buy for the 2003tls? Is this something i can install myself? or if i were to get them installed, what kind of a ballpark price are we talking for the install. Also do i have to change the factory mufflers when i do this. Sorry for the lame questions, just don't really know what i'm getting myself into? does putting on these headers really improve the performance? Does the sound change? thanks guys in advance, your input would really be appreciated. Got to get this done b4 the wife changes her mind. you know how women are!?

 

This should help. Take care.
