Ok that is my car the OP posted so you know what I think
I don't think the Von Hep is offered anymore
I love it and have had no issues with the header wrap on the elbow.
My calculations have me right around 25 lbs. savings including scrapping the stock exhaust, rear panel, and heat shield.
If you can find a Von Hep I say go for it. Looks great and the sound is amazing.
