X-PIPES
Since V8’s fire unevenly, exhaust exits in pulses rather than 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 quicker and this better ‘breathing’ increases horsepower.

High quality, exceptionally versatile design and performance define our crossover product line. They are a proven winner when it comes to bumping up the horsepower of your daily driver or race car. Our universal X-pipes fit an overwhelming variety of classic cars with extreme ease of installation. Our model-correct kits install like a dream. There’s no skimping on materials here. All crossovers include dual 409 stainless reinforcement plates at the welds where they are needed most. All pipes are are mandrel bent, to allow for the maximum flow of exhaust gasses, which boosts acceleration. Fabricated using the highest quality materials, our smooth, seam-coated, mandrel-bent, 409 Stainless Steel pipe resists corrosion and extends the life of your system. Check out our industry first X-Change version of our crossover. It allows you to open and close your exhaust with the bolting or unbolting of dump plates or for a real attention getter, our electric cutouts bolt right on!
