These free-flowing, mandrel-bent Pypes H-pipes have reinforcing plates at
critical locations. They are available in 409 stainless steel for years of high-powered performance. Since V8s fire unevenly,
exhaust exits in pulses rather than in a steady flow. While one pipe is filled
with pressure, the other pipe is relatively pressureless, but the connecting of
the two pipes in a siamese pattern allows pressure to be released to the other
side. This action allows the exhaust to pass through the pipe more quickly, and
this improved 'breathing' increases horsepower. Pypes H-pipes' high-quality,
exceptionally versatile design and performance make them proven winners when it
comes to bumping up the horsepower of your daily driver or race car. There's no
skimping on materials here. All crossovers include dual 409 stainless
reinforcement plates at the welds, where they are needed the most. All pipes are
mandrel-bent, allowing for the maximum flow of exhaust gasses, which boosts
acceleration. Fabricated using the highest quality materials, these smooth,
seam-coated, mandrel-bent, 409 stainless steel pipes resist corrosion and extend
the life of your system. The kits include the H-pipe with extended legs and installation hardware.
