Different versions of IPE Exhaust?

[Spun Crankhub]

Looking around at the different valved exhausts and I have noticed there is an F1 and Evo version. Is there a difference in the cans, or is it just about the X pipe? Thanks guys.

I think they're the same

X pipe is the only difference. The rear section plus test pipes is absolute bliss. Few things are more therapeutic.

That is what I thought, and yeah sound clips I have heard are incredible!

So IPE do offer an F1 version and an Evolution version of this muffler. They also charge about $1000 USD more for the F1 version.

Anyone compared the two rear mufflers with the same x-pipe or heard either in person? Wondering whether they're just going to sound the same and it's all marketing, or if there is actually a different muffler design?

I thought both the evolution and F1 systems share the same muffler, with the difference being that the evolution system has a catted x-pipe and the F1 system has the gimmicky catless x-pipe.
