I bought a shmick mk4 R32 exhaust cat-back from a fellow forum member (word Dainese) and am now getting conflicting reports on the status of the cat.
Some members suggest that the catalyst material disappears or degrades over time, and so the cat is rendered useless.
Others have said they can get blocked.
Still others have said that it is totally fine and not to drop the $400 on getting a replacement "hi-flow" cat.
Can i get a relative forum consensus here please?
