Mandrel bent pipes increase airflow.

This all-inclusive kit from Pypes Exhaust has been designed specifically for street machines and muscle cars. Each kit comes with a precisely engineered X-pipe to equalize exhaust gasses prior to entering the mufflers. All kits are available with a standard X, while others are offered with the exclusive X-change which features additional outlets giving you the option to run your exhaust through mufflers, or uncap the legs for an open system. From the heavy-gauge mandrel bent stainless tubing to the TIG welded stainless steel mufflers, these kits are designed to last for years and provide the smooth sound you desire. Kits also include tailpipes, zinc clamps, and stainless steel hangers to aid installation. The complete systems are compatible with original exhaust manifolds or aftermarket headers.

  • Connection to exhaust manifolds will require the use of OEM-style down pipes available from OPGI for both small-block and big-block.
  • Due to tooling restraints, some of the tailpipes may have a welded joint located above the rear axle. Once installed, this joint will be hidden and will not affect performance.
  • Using either aftermarket headers or stock exhaust manifolds may require additional hardware.
  • These high-performance items are not eligible for any further discounts or promotional pricing.
