These free-flowing, mandrel-bent Pypes X-pipes have reinforcing plates at critical locations and are available in 409 stainless steel or polished 304 stainless steel for years of high-powered performance. Since V8s fire unevenly, exhaust exits in pulses rather than in 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 more quickly and the improved 'breathing' increases horsepower.
I bought shorty headers and single chamber mufflers to go with the x pipe and my car sounds great!!! I thought it might be a pain cutting the catalytic converters off but I laid the x pipe on top of the stock h pipe for length and it was a piece of cake. It freed up some extra ponies by making the engine breathe better, thanks for a great piece of my on going project!!!
