He works at the dealership. They definitely would list it for around 6k.
they still have to make profit off of him even though he works there.
It's the exhaust side you really have to worry about, not the intake side...it's all for noise for the most part. Gotta love the blower whine though, it's quite a bit different than the M62.
If you plan on DD'ing the thing, just plan on a 3" catted downpipe...or catless if you can get away with it. Leave the catback alone...it's not restrictive. The factory front manifold, downpipe, and the u-bend are the parts that need to be addressed.
A bonnie guy tested that. Accordian didnt affect anything.
