Free-flowing, mandrel-bent Pypes Street Legal X-pipes have 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 pipe more quickly and the improved 'breathing' increases horsepower. Their 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, mandrel-bent, 409 stainless steel pipe resists corrosion and extends the life of your system. They include the X-pipe with extended legs, cutout covers, cover hardware, and installation hardware.

Steeda Mustang 5.0L Coyote 304 stainless resonator delete crossover pipes are the best way to improve sound and increase performance at minimal cost—while losing up to 6.5 lbs. of weight. Available in X-pipe and H-pipe models, the design increases torque at lower RPM and delivers a traditional mean, deep muscle car exhaust tone. The layout enables you to retain the factory heatshield found on 2018 and newer GT models—without cutting and expanding the crossover pipe to retain the OE shields or chiseling off the OE shields. With mandrel-bent 2.5 in. diameter tubing, these crossover pipes easily install between the factory catalytic converters and the factory mufflers. They're also compatible with virtually all aftermarket axle-back exhaust kits. The 304 stainless steel tubing will not develop surface rust typical with 409 stainless, nor rust completely through like aluminized mild steel. The flush-fit exhaust clamps allow for shortening the pipe, if needed, and prevent exhaust leaks common with expanded end kits.
