Exhaust System Tech, Myths and Much More...with Magnaflow's Rich Waitas
About this episode
MagnaFlow’s Rich Waitas joins OnAllCylinders host David Fuller on-site at MagnaFlow’s Oceanside facility to break down exhaust tech beyond “bigger pipes = more power.” They tour the R&D process, explain how modern PCM control limits exhaust changes, and debunk myths with flow-bench results showing a straight pipe can flow less than a perforated-core muffler. The discussion covers scavenging, why h-pipes vs x-pipes differ for sound and pulse interaction, and how MagnaFlow uses NDT and modular systems (like XMOD) to dial out drone while keeping desired tone. They also outline product development by vehicle use case (street, competition, overland, neo) and offer buying/install guidance.
We get to the bottom of some common exhaust system myths and talk through popular debates like X-pipe vs. H-pipe. To find definitive answers, we traveled to Magnaflow Exhaust and talked to Magnaflow's Rich Waitas. We also discuss exhaust system choice and go over some things to consider when buying an aftermarket exhaust system.
