Is the SVR Mid Pipe different from the R Mid Pipe?

Curious, because when you buy a R Mid Pipe on any of the OEM sites. This is what it shows for Vehicle Fitment.

Are they interchangeable? Jaguar just labeling Mid Pipes for SVR and charging more?

 

The SVR spruiks an Inconel / Titanium exhaust system but I have always wondered how much / which bits are Inconel / titanium and which bits are stainless steel such as for the other V8s, I have never read of any details on this.
So it is possible that the mid-pipe in question costs more for an SVR coz it is Inconel / Titanium but who knows!
My guess is that even if it is Inconel / Titanium it is exactly the same size and shape etc as the cooking SS version and the two versions are interchangeable.

 

I learned something new today. "Spruiks." Thanks, Oz! :-)
