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

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.

 

Louder than a 3?

 

Yeah, 3 is (counterintuitively maybe) the quietest. They all sound the same when bypass is open, the level refers to the amount of muffling on the primary.
