[A4] How much for a catalytic converter for my A4?

[aaron]

If your car has over 140k on it...the cat is prolly toast....especially if you are 
running any aftermarket software or let the car run rich for long periods of time.  I 
found it cheaper to get a "high flow" cat from Techtonics Tuning that to buy an oem 
one.  Plus the hi-flow cats are a great perf. mod.!
