im pullin the cat tomoroww at the shop but i havnt measured my exhaust yet so does anyone know what size tubing i will need, the exhaust is stock on my 93z A4 so im guessin maybe 2 1/4?? its going to be welded so i dont need oversize tubing, just same size as stock piping at the cat.

 

oh and also if any of you guys want me to add your car to my new site just send me an email of all your mods and some pictures. Jason@dragonperformance.com the site is pretty new so it would be cool to get a couple nice f-bodies up on the rides section
