Pypes 2-1/2" Stainless Steel Tunnel X Crossover

Since a V8 fires alternately, exhaust exits in pulses rather than a steady flow. While one pipe is filled with pressure the other pipe is relatively pressureless, but connecting the two pipes in a Siamese pattern allows pressure to be equalized between the two tailpipes. This action allows the exhaust to pass through quicker for better breathing that increases horsepower.

Made of 409 stainless steel with dual reinforcement plates at the welds where they are needed the most and is mandrel bent to allow for the maximum flow of exhaust gasses, which boosts acceleration.

Limited Lifetime Warranty.

Important: If using stock, cast iron manifolds, add a set of down pipes to connect your ori ginal manifolds to the crossover.

Note: Shipped oversize.

Camaro / Firebird Application Notes: Modification to the body pan brace is required on 1967-69 Camaro or Firebird convertible models. In order to utilize this X-pipe, it is necessary to either add a body pan designed to allow clearance for the X-pipe assembly, or remove the body pan and install subframe connectors.
