All of Pypes street legal Mustang catalytic x-pipes utilize small, but mighty, ODBC compliant, catalytic converters. They out-flow most performance mufflers and weigh a mere 2.5 lbs. These are designed specifically to give your Mustang a major wake-up call in both sound and performance. The modular design of these x-pipes allow for conversion from off-road to street-legal and back to off-road with optional cat-delete pipes. Pypes' Catalytic Converter X-pipes will pass emissions inspections in most states. Check your local and state regulations for installation and usage guidelines. Gain 8-12 HP and a unique sound!

Pypes Mustang X-Pipe Science
Since Mustang V8’s fire unevenly, exhaust gasses exit in pulses rather than 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 quicker and this better ‘breathing’ increases horsepower. This science is forwarded to the V6 community to offer the same style performance and unique sound!

Pypes Quality
High quality, exceptionally versatile design and performance define Pypes' x-pipe product line. They are a proven winner when it comes to bumping up the horsepower of your Ford Mustang. There’s no skimping on materials here. All Pypes x-pipes include dual 409 stainless reinforcement plates at the welds where they are needed most. All pipes are are mandrel bent, to allow for the maximum flow of exhaust gasses, which boosts acceleration. Fabricated using the highest quality materials, Pypes' smooth, seam-coated, mandrel-bent, 409 Stainless Steel pipe resists corrosion and extends the life of your Mustang's exhaust system.

Installation Notes
