Has anyone used this replacement cat in a e430 4matic? If so, how long? Has the car performed as well as before.
Thanks for your comments

The vast majority of aftermarket cats discussed and recommended here have been the Magnaflows. What are you trying to accomplish by using these DEC units?

Nothing wrong with DEC. But if you're in CA you can't use them.

So back up, click user cp and complete your profile for vehicle and location, it's useful information.

I am in the market to replace two noisy cats. The DEC units replace both front and back cats so it avoids the risk of having to revisit the repair. On the subject of magnaflow which model fits rear cat on the e430 4matic?
