PC-29 / 1967-1982 Chevy Pulse Chamber

MPI Pulse Camber #29 

The MPI Pulse Chamber PC-29 is designed to fit all 1967–1972 K5 Blazer, C-10, and Suburban models with 4-wheel drive, as well as select 2-wheel-drive applications. It is engineered to balance the two unequal-length exhaust banks by mixing and merging all exhaust pulses through our patented Pulse Chamber technology. 

This Pulse Chamber can be installed either above or below the driveshaft, allowing for a clean, professional installation on your classic hot rod or restoration project. It eliminates exhaust drone while reducing interior sound levels, all while maintaining the vehicle’s existing exterior sound level. Balancing the exhaust banks creates a smoother, more refined exhaust tone. MPI's pulse chamber doesn't rely on a restriction to minimize in-cab drone effects, unlike the Common x-pipe. Our product provided a better performance increase than any x-pipe or H-pipe on the market to date. 

The flow capacity is suitable for engine sizes ranging from 3.6L to 6.4L. Available in either aluminized steel with a 3-year warranty or 409NI stainless steel for a bright, durable finish, backed by a lifetime warranty. Proudly built right here in Montana.
