A couple shots of the exhaust. I used a correct 30° collector and all thickwall mild steel pipe from Racing Beat. The two 'hotdogs' are glasspacks. The small one is from a friend's baja and seems to be of better build quality than a typical cherry bomb from the auto parts store. The big one is a Rotary Engineering glasspack that is nearly 20 years old and did a great job quieting my 20B. The small one is over ten years old and quieted his VW powered baja well enough (it can be seen here). The paint is mainly for rust prevention but does look decent. It's a high temp paint. I expect the u-bends to get hottest and help quiet things down as the exchaust gasses change direction; a convenient way to take energy out while not necessarily restricting flow. Velocity should remain high at low RPM for good power from idle up to where all the curves begin to cause restrictions. If this system runs out of breath by 6 or 7 grand, that is just fine.
