I almost hate to sound contrary but me no likey.

For one, it doesn't look like the header tubes are equal lenth, although a shot of the bottom of the engine might show otherwise. Second, it looks like the second 2-1 collector diameter is the same at the header tubes, which would cause a major restriction. Third, real tight adjusting the valves.

The fit and finish appear to be top notch, but I'd rather have ugly if it means better flow.
