X-type dual exhausts help engines make more power by reducing exhaust reversion and scavenging cylinders better, to counter the uneven exhaust pulses of a V8's firing order. With Summit Racing™ universal X-pipe kits, you can fabricate a custom "X" system for just about any performance vehicle. Kits are available in several large tubing diameters and include all of the essential pieces--that means four 45 degree mandrel-bent sections of tubing (which you trim to size), the prefabricated X-section that is the heart of the systems, and the heavy-duty clamps to hold them all together. They're made for off-road use only.

Let your engine breathe easy! Pypes off-road X-pipes are free-flowing, with reinforcing plates at critical locations and are available in 409 stainless steel or polished 304 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 pipes quicker, and this improved "breathing" increases horsepower. Pypes X-pipes' high-quality, exceptionally versatile design and performance are a proven winner 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, the smooth, seam-coated pipes resist corrosion and extend the life of your system.
