Default What are the best CATS to put on my A4 B5??

Had my car in the shop for inspection and they told me the exhaust had some holes that needed welding. When I got the car back one of my CATS was rattling horribly...I know it's not a heat sheild it's actually inside the CAT. I just wanna know what would be the best CATS or test pipes to buy to replace on my factory exhaust system...PLEASE HELP!!!

"Best" depends on your intentions for the car, but you can get high-flow cats from Magnaflow or Random Technology, or OEM cats new at a dealer or used from someone parting out their car. OEM is direct fit obviously. High-flow breathes better but may require adapting pipe diameters.

I'm just looking for one's that will fit to the stock pipes, but can also offer some performances. Because I'm looking to buy a Magnaflow 14816 muffler at the end of the month too.

What kraut said, hard to give advice with no knowledge of what motor your B5 has.

just go to ecs tunning or any of our "performance" sites and order them... or you can do like the s4 guys and yank them out and "piggie" them(hollow)
