After reading all the posts about having trouble with the meganracingwholesale.com site I decided to order the exhaust from Aptuned.com which is the sister site for Redline360.com (receipt says Redline360.com).
I checked with Megan Racing and Redline360.com (aptuned) is an authorized dealer of the Megan exhaust. I contacted Dan at redline360 and ordered the exhaust through the aptuned site because for some reason the redline360 site did not have the e92 exhaust listed and paid $499 (sedan price was $479). Dan was more than helpful and got the exhaust shipped (with fedex confirmation) the same day I ordered it.
Hope this helps those looking for a place to purchase this exhaust.
