i have an 04 black on black TL . 6 spd. i have xlr8 quad exhuast.

1. has any one had a problem with an AEM CAI wihtout a byass valve. i have one in my garage but im afraid to put it in wihtout a Bp valve.
2. all ive doen is exhaust. i like back roads a little more then straight aways but my car isnt an S4 so...

honestly with 1000 dollars what would you do to make this car faster.

if not faster better handling?

thanks
very curious

 

Ive got Teins SS, and corners like its on rails hehe if your looking for handling.

 

Def. upgrade ur suspension with a rear sway bar for handling. And performance i would get a j-pipe for sure. Then Pre-cat deletes if u dont mind noise, smell, and inspection issues.
