I'm Confused

You need no extra bolts. I also did not order extra gaskets on the down pipe side. But you have to be careful then. Maybe it s better to order some new ones.
From the RealOEM website, (, part number 18307599743 shows the secondary catalytic converters. RealOEM's diagram can be seen here.

The picture that Dackelone posted in this thread shows no secondary cats. Am I to assume that RealOEM's diagram is incorrect? I suppose I could order through my dealer and inspect upon arrival to verify.

One other question: with the elimination of the secondary cats are exhaust emissions affected? My home state here in the USA requires an annual safety and emissions inspection and I want to make sure nothing changes so the vehicle will no longer pass their testing.
