Pypes 99-04 Mustang Catted X Pipe

Our model-correct kits install like a dream. Theres no skimping on materials here. All kits 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, seam-coated, 16 gauge, mandrel-bent, stainless steel pipe resists corrosion and extends the life of your system.

All of our Street Legal crossovers utilize our small, but mighty, 5.0 litre ODBC compliant, catalytic converters. They out-flow most performance mufflers and weigh a mere 2.5 lbs.

Pypes cats and catted X-pipes will pass most states emissions testing procedures. However, check your local and state ordinances for installation and usage regulations.

**rich conditions, unburnt fuel getting into the converters, or oil getting into the converters can cause converter failure and is not covered under the warranty.
