Audi B6/C5 3.0L "test" downpipes
4ringking has come up with a problem free solution for the 3.0L P0421 or P0431 faults. After extensive R&D and on the road testing, we have the permanent fix to the 3.0L faulty catalytic converter problem.
JAAWS 3.0L "test" downpipes!
Includes: Right & Left Bank, 3.0L OEM modified "test" downpipes with OEM main cats, O2 Bung Plugs, and relocated rear O2 sensor bungs. NOTE: The rear 02 sensors need to be relocated behind the main cats, the stock rear O2 wires are long enough if done properly. Cost per pair $325 plus shipping.
Options:
-Automatic quattro, CVT front wheel drive, or Manual Transmssion
-Vibrant Performance Flex Section Replacement, add $175 per pair.
-DEI Exhaust Wrap, add $40 per pair.
-Core Charge: Turn around time on this service is 7 to 10 business days. If you can't afford to have your car apart and have your downpipes modification, we do offer sets already complete. You just pay a core charge ($200 per pair), we send you a set then when you ship yours back to us we credit you back the core charge.
NOTE about cores: You may receive a pair of main cats with different mileage than the ones on your car if you opt for the core option. Example, if your car has only 30k miles an you buy them from us with a core charge then we could be sending you downpipes with 15k, 20k, the same, 50k or 75k+ miles.
NOTE: Since the rear oxygen sensors are moved as part of the modification, technically these downpipes are not legal in the state of California and some other states (check your state laws for details). Obviously we sell these as an "off road" use only downpipes.
