What Killer B Motorsport does

Killer B Motorsport is a privately held, family-owned U.S. manufacturer of aftermarket performance components for Subaru vehicles, founded in 2008 and operating from Waynesboro, Virginia with a team of approximately seven employees. The company designs and builds components across four primary categories: oiling systems (cast aluminum oil pans, ultimate oil pickups, air-oil separators, catch cans, oil control valves), performance exhaust (321 stainless steel "Holy Headers," up-pipes, V-band hardware), engine-bay parts (dual reservoir washer/coolant tanks, breather fittings, turbo studs), and interior accessories (Delrin shift knobs). Its core engineering approach centers on 3D CAD design, CNC manufacturing, and digitally pulsed TIG welding, with a notable differentiator being its status as the only manufacturer of full 321 stainless steel headers—an aerospace-grade alloy chosen for high-temperature turbocharged applications.

The business operates a product-led, direct-to-consumer e-commerce model through killerbmotorsport.net, supplemented by a dealer/distributor wholesale portal accessed via application. Pricing is per-unit (no subscription model), ranging from roughly $6 for small hardware items to over $2,000 for premium header assemblies, with tiered dealer pricing. Its customer base is a narrow vertical: Subaru performance enthusiasts who own and modify WRX, STI, BRZ, FR-S, and GR86 platforms for street and track use, with secondary exposure to performance parts retailers and distributors. The company emphasizes domestic manufacturing, quality inspection prior to shipping, lifetime warranties on multiple SKUs, and community engagement through NASIOC forum presence and a YouTube channel. No external funding, acquisitions, or parent company have been disclosed; the firm was founded by Chris Bergeron and is now owned and operated by his wife Hollie Bergeron.
