1964-1977 Chevelle Pypes X-Crossover, 3.5 Inch 409 Stainless XVA14

High quality, exceptional design and performance define the Pypes crossover product line. They are a proven winner when it comes to bumping up the horsepower of your daily driver or race car Chevelle. Our Driveshaft Tunnel X crossovers fit a variety of classic cars that are prone to limited ground clearance.
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 mandrel bent, to allow for the maximum flow of exhaust gasses, which boosts acceleration.
Fabricated using the highest quality materials, our smooth 16 gauge mandrel-bent, 409 stainless steel pipe resists corrosion and extends the life of your system.
This crossover is the big brother of the XVA13. IT has all the same features except the 3.5 inch tubing will cover cars with horsepower ratings in excess of 700hp! This siamese design crossover yields 20-40 additional horsepower, depending on application.
