I am selling my 2001 S4 Tiptronic, 71k miles, gorgeous in and out BUT:
I need to replace the catalytic converters. They are clogged with oil from turbo failure. Turbos were replaced under extended warranty.
Can you'all please call your local tuner and see if they have a set of catalytics that they took off a car to install an exhaust upgrade? Remeber: Tiptronic...
If you can find me some and they work, I'll pay you $200.00 as a finder's fee
Another option is, if you want to buy the car as is, and install an aftermarket exhaust, I'll discount it.

 

Solution to the cats, get a crowbar and a hammer and hallow out all the ceramic/fiberglass. This will probably actually improve performance and make the car louder, but most likely fail smog. This is of course the cheap version but thats what I would do. How much are you selling it for?

 

Thanks for your advice.
I need to sell a car with correct emission standards, unless someone wants to buy the car as is, and replace the exhaust system.
Frankly, I am disappointed by this forum. I read a lot of stuff about people out-running BMW's, EVO's, etc... but little useful information or help. Just check the "replies" on serious issues, vs. the replies on "I smoked a Mustang" or such crap...
Sounds like a bunch of teenagers with latent road rage!
I'm off to Audi World for advice...

 

Haaha lmao if you willing to pay a finders fee of $200 why dont you just go buy new cats and have them replaced.... or u got extended warranty soo have them replace them... ORRR if you just wanna get the car out of your hair get universal cats that will work fine with the car and last time i checked at my shop the highflow cats were maybe $150 each if that... but please shut me up if you need a "special" one.

And on the other hand, you asked if anyone had any around.... so if u get no responses then i dont think there is any around.. and idk but most people here are also on audiworld. so hey Apples or Oranges. good luck with you sale and cat searching
