Just curious, I see on the website that there is now an exhaust package for sale that looks just like the one above, but advertises 371 whp, instead of the 362 whp for the one in the posts above. What's the difference between these setups that gives the extra 9 whp?

Guessing here but it could be the Cup option that deletes the valves.....

Muffler Weights for those that intend to go with the TPC Exhaust Conversion Kit:

GT3 Steel - 15lbs 9.0oz
GT3 RS Ti - 9lbs 4.0oz
Akrapovic GT3 - 13lbs 0.6oz

I have all three.

As part of my partout, I thought I would shoot one last video of my exhaust. This is the TPC kit with an Akra GT3 muffler. Thank you TPC for making this kit. It just transforms the GT4 into aural heaven.
