Actually, to put it on a Tomos, you can use a 2-piece Biturbo, which is actually designed to put a Puch Athena kit on a Tomos bottom end. The angles are all correct for it.
The Tomos 2-Piece doesn't actually bolt up to any Tomos Kits. You can use it to put pretty much any Puch flat exhaust kit on an A35 or A55.
As for the intake, this is the intake that was again originally designed to put a Puch kit on a Tomos with Dellorto carb.
The intake is pretty pricey though, we don't have any in SF, but we could ship directly to you from our Distro.
