    So here is the scoop. I just installed the tubi and between the muffler and Y-pipe there is a butterfly valve that opens via vacuum pressure? not sure. Anyway, where I got the pipe from, they told me it would eliminate that butterfly valve. Guess what? still there. I called and told them I was pissed so they said they would find out by calling the shop. Comes to find out that there is a way that you can wire a switch to this butterfly valve so it is open all the time. As you all know, this is my first Ferrari and first 355. I didn't know better. Is there a straight pipe for this? The place I bought it from says I should keep the valve there for residential neighborhoods. I can agree with that. Help!?!?

    Hi Xavior, Do a search under my name(can't remember the title of the post) about 3 or so months back there is a post I commented on along with others on CELs coming on and the reason that they may if you remove the that valve at low rpms. I'm just to lazy to repost my comments(hate to type), sorry. If you have any further questions feel free to ask. Regards, Vern
