F355 ITO Racing Exhaust (Japan) .... better than Capristo??

Capristo pitch is nice no doubt, but that I can’t get over that Jekyll & Hyde personality on a 2.7 your vid clearly demonstrates (the contrast from closed to open). Just as when you’re about the get some F1 sound, it cuts off while you let off. The progression doesn’t seem right. The 5.2 seems to do a better job although pitch is less.

A level 2 or 1 would have less of the Jekyll and hyde nature. I like the 3 as this was a 1500 mile trip total and 90% of the time the valve closed volume was good to have. That last 10% I'd just pin the valve open. I tried to fashion something on the trip but would have had to at least remove the air boxes and cover to do so, so just left it. I'm really glad I didn't run the open challenge exhaust or I'd probably be deaf.

On my 5.2 there was no difference between Cap 1 and Cap 3. Pretty sure it's a marketing gimmick

I had a 2 previously (when I bought the car) and it was definitely louder when the valve was closed.
