Default X-Pipe Question?

Just got my car today, arrived from FLA. It's a 2005 Roadster, LS2, A4, Completely stock with 3.15 rear end gears. I want to put on either a B&B Bullet cat-back exhaust, Vararam Intake, and 3" Off Road X-Pipe. I know I don't need a Tune with the intake and cat-back but will I if I add the off road X-Pipe? Does anyone know? TIA!

Definitely. You will need to turn off the 2 rear O2 sensors or it will throw a DTC due to the cats being missing.

Congrats on your new toy! A tune might also be worth it to pick up a few more hp/tq over the stock ECU programming.

Agreed! Stock is ok but with a tune is pure FUN!
