Kraken is a manufacturer, not a reseller. The turbo manifolds are cast in-house from NiResist D5S Type 2, a high-nickel iron that resists cracking under sustained heat, unlike the welded steel tube most competitors use. Downpipes and exhausts are TIG-welded in-house from 304L stainless, matched to the manifolds and machined to the factory mounting points without shims. More than 4,000 cars now run Kraken hardware, built for one car: the Mazda Miata.
The manifold, downpipe, wastegate and exhaust are matched in one pass, priced as you build it.
