good day folks
So apparently I need a new catalytic converter for my car. The repair and part aren't that cheap and now I'm thinking of getting downpipes instead, so my question is it better to get downpipes cause they seem cheaper? if I do that I don't really need to replace converter at all right? And Do I need a tune before i get downpipes? how exactly it works? thanks
Will not pass emissions test without the catalyst.
The catalyst burns any uncombusted fuel left in the exhaust. You need it to pass inspection. Catalytic converters aren't a common failure, so you might look into why it failed before buying downpipes and a tune. If you have oil leaking from your turbo or valve stem seal, that money will already be spoken for. Generally cats go bad from excessive oil or gasoline in the exhaust, or running leaded race fuel.
I agree with what Rocket Surgeon said. Get your car checked out. If everything checks out, I'd go ahead and get the downpipes. They won't pass emissions though
