These headers are equal length tri-Y designed for low end torque. For whatever reason they work great on the top end as well. Mandrel bent, progressively staged with 1 5/8", 1 3/4",2", 2 1/4" and 2 3/8" pipe. Primaries are 15-16" and secondaries are about the same, depending on the day of the week they are built. Our dimensions and the stepped technology make these the best on the market at any price. Performance improvement ranges from 3 to 10 HP increase over stock and other header designs. There is proper fit and clearance all around for all 105 and 115 Alfas. Black ceramic finish shown here. We also stock them unfinished or with dark gray ceramic finish.
