Yeah, looks like the same one, glad you're pleased with it, I'll have to get my order in!
The gasket you're talking about is where it meets the manifold I guess? What cat-back system have you got? Did it connect with that ok? I'm all stock exhaust at the moment and was just planning to change the DP and keep the stock cat-back. Is there any noticeable noise difference?
Cheers,
Pete.
