PLM パワードリブン Bシリーズ ダウンパイプ（ラムホーンダーボマニホールド用）B16 B18 B20

The 3-inch mandrel bends are smooth and the 304 stainless feels solid, no kinks or thin spots. I had to weld on an extra bung for my wideband, but the two factory ones are well-placed. Fit my ramhorn manifold perfectly with the included v-band and clamp.

The v-band and clamp made connecting to my turbo a breeze, no leaks at all. With the two O2 sensor bungs already in place, installation was way simpler than I expected. The 3-inch mandrel bend piping really opens up the exhaust flow nicely.

The 304 stainless steel feels solid and the two O2 sensor bungs saved me from having to weld extra ones on. Bolted right up to my ramhorn manifold with zero leaks.
