Yes, Grant. It sounds pretty much the same too.
since we're talking about challenge exhausts. this is the Fabspeed challenge setup. which has very recently been removed from my car and available for purchase. Image Unavailable, Please Login
The Tubi race muffler and Tubi Evo both mimic the factory race and street exhausts. It's the old Tubi that doesn't have separate exhaust paths. Here is the Tubi Evo: Image Unavailable, Please Login
Elliot I take it you have a internal or cutaway view. I thought when they both come out of muffler equals same path?
I don't need a cut away view. I have owned both the older Tubi and the Tubi evolution. Here is the Tubi Evo description: The new Tubi Evolution Sports Exhaust is designed to optimise the sound resulting from this layout. The new Tubi contains two separate mufflers for each of the two exhaust channels, but combined into one exhaust. There is a conventional Tubi muffler below 4000rpm (which may be specified in either a level 1, 2 or 3 configuration, depending upon your preferences) to give the 355 that classic deep, full, throaty "Tubi sound". But now, instead of sending exhaust flow into the same muffler at 4000rpm, exhaust flow is sent straight out to a direct-exit channel, thereby minimising back-pressure and optimising the 355's fabulous V8-engined howling scream.
Can you detail the basis of this? ^^. I may very well be wrong but as far as I could tell with mirrors, the bypass path of the capristo 2/3 is completely divorced from the primary path. Looked like it just "teed" into a pipe leading directly to the tips. I do find it interesting Ferrari found it necessary to add secondary cats and a bypass valve. Even 22 years ago I would have thought it to be easier and cheaper to run larger main cats that were not restrictive. Maybe they wouldn't light off fast enough.
This is correct. The primary and secondary pipes are separate for their racing and regular exhausts. Main cats lead to the outer tips. Inner tips are for the bypass. This description is in paragraph four from their website. http://www.capristoexhaust.com/ferrari-355/ferrari-355-sound-3-racing-exhaust-systemt.
Yes. And here's the Challenge muffler for noise-restricted tracks... . Image Unavailable, Please Login

That was what I was told by capristo about 6 to eight years ago. What he told me when I enquired to get his exhaust was the twin valve did not sound as good but it had completely different paths. It was new at the time and I belived their propaganda on that it would benefit the headers in the long run. I do not know from examining their old exhaust but just by what he said at that time. Obviously yours is diffenent and Elliots new tubi is different. Thanks for sharing and correcting me. I would point out then they all are not necessarily what they appear to be. I was under the impression when they shared the same muffler housing it was one muffler not two separate mufflers.
