Moving from bolting parts to burning steel is the ultimate step in creative freedom, but stainless steel brings its own set of rules. The guys welcome Mark Prosser once again to the podcast to discuss stainless welding tips, including why dedicated wire brushes are a must and how to balance amperage with travel speed. From the metallurgy of 304 vs. 321 alloys to the high-stakes world of back purging, Mark breaks down why stainless is a unique beast compared to mild steel. Whether you’re building a turbo manifold or custom exhaust, discover how to use gas lenses, manage thermal expansion, and nail "the dip" to achieve those perfect, Instagram-ready welds. 

While SEMA is the "bling," AAPEX is the "soul" of the automotive industry - where the daily drivers get fixed. Live from AAPEX 2025, Kevin and Willie sit down with Dustin Pedley from bproauto to discuss how they leverage the massive engineering footprint of Stellantis and Mopar to create "Next Level" parts, using the same engineers who validate OE parts to ensure aftermarket reliability. Discover how they use "inside baseball" knowledge to identify common OE failure points and engineer them out of their aftermarket components—offering high-tier quality for everything from 1970s classics to modern daily drivers. 

Direct from SEMA 2025, Kevin and Willie explore what it means to be "Built Different" with Carlyle Tools’ Joe Sabo and the company’s latest sponsored NHRA Top Fuel driver, Maddi Gordon. The guys get hands-on with gearless ratchets, drill bits that won't walk on diamond plate, and the world’s first creeper with a kickstand. Joe explains the philosophy of designing tools for how they are actually used, while Maddi shares her new journey of representing the brand both as a "wrench" and as a driver of an 11,000-horsepower "Venom Green" dragster for her rookie Top Fuel season. Discover how Carlyle is inspiring a new generation to build professional kits without the burden of "tool truck debt”. 

Willie and Kevin are live again from the SEMA Show floor as they sit down with Matthew Palumbo and Don Zaney from Stinger to discuss the evolution of the vehicle “command center." Learn how Stinger uses the world’s largest CAN bus library to bring 12-inch displays, integrated lighting, and multi-camera views to everything from '57 Chevys to modern side-by-sides. The guys explore Stinger’s latest innovations, including rock lights that trigger based on steering angle and glove-friendly touchscreens designed for direct sunlight. From waterproof displays to multi-camera kits that help you navigate the trail, learn why the modern infotainment system is the ultimate tool for both the highway and the backroad. 

Kevin and Willie kick off their 2025 SEMA Show interviews with Bartec to discuss one of the industry's headaches: TPMS. With over 150 communication protocols, tire pressure diagnostics can be confusing for technicians and DIYers alike. Scot Holloway reveals how Bartec’s Tech600Pro and universal sensors are turning complex issues into five-minute fixes. Whether you're a shop owner looking to turn TPMS into a profit center or a car enthusiast tired of the "blinky light," this episode covers the TPMS tools and tech you need for 2026 and beyond.
