MagnaFlow 2×3インチ 4-1 パフォーマンスエキゾーストヘッダーマージコレクター 10803

The welds are clean and the stainless steel feels heavy-duty, which gives me confidence it'll hold up under heat. Bolted right up to my existing header tubes with no alignment issues. Definitely noticed a smoother pull through the mid-range on my first test drive.

The collector’s internal merge spike is clearly machined, not just cast, so flow should be smooth. Fits my headers perfectly and the welding is clean, no slag inside.

The merge collector’s 4-into-1 design makes a noticeable difference in scavenging—my custom header build pulls harder up top without any fuss. The stainless construction feels solid and should last through plenty of heat cycles.
