Just got mine swapped. As in put a 3.4 fister on my 40th anniversary which had a superspirnt w xpipe. I kept the xpipe on the 40th.

While I appreciate the drone being gone, the car doesn’t sound anywhere near as good as the 996.1 with the same cans. Also maybe it’s butt dyno or selection bias. The car feels a little slower now.

I was hoping for this
but now I got something equivalent of a vacuum cleaner. Sigh!

The answer to my very first world foibles maybe found by just getting a set of 3.6 mufflers from fister and exchange the 3.4s cores out, if he will do it.
