Lawd hammercy yall. We're supposed to be family here.
The slant six and every inline six I'm aware of has a firing order of 1, 5, 3, 6, 2, 4. Look how that lays out when you split the exhaust ports into two pairs of 3. Each fire of the stroke swaps to the next pair of 3. It's the perfect layout for great scavenging. The Clifford shorties WILL BE tri wye headers when you connect them together with the third wye "SOMEWHERE" under the car into the single exhaust that inline engines "should have" for the most efficient scavenging anyway. Putting duals on them loses the scavenging effect of that "third wye", which is the reason I always recommend a good HP single exhaust on a slant 6 over duals.
