Need some input

[Rdhop613]

I run a straight pipe from my cats back on my RS6. I'm thinking of removing the cats and getting borla mufflers. I heard by removing the cats I'll most certainly need a retune on the car. Is that true? And any suggestions on a different muffler to purchase. I'm not worried about droning sound. Artillery made sure low noises don't matter any more. She can almost be obnoxious. Let me know

well you will at the very least need a code out of the rear 02's

What does that entail?

you'll need a tuner that can create an ECU map with that functionality disabled.

Ahh very well! Might have to take a trip to the boys at RSW if I decide to do a cat removal. Thanks for the heads up.
