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.
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.
Installed this on my 2003 Mach 1 in a few hours. The welds look solid and of good quality and the overall workmanship is actually much better than you would expect. Only issue I had was that the 02 sensor bungs on the main downstream pipes coming from the headers were placed slightly too low by about 3/4" so the 02 sensors would not reach the harness, unplugged the connectors from the transmission harness and was able to get just enough slack for the sensors to reach. This was still a great bang for the buck upgrade, sounds great, and car feels more responsive.
