Are these pipes stainless steel?
Yes. The WCF100589 kit is constructed from high-quality stainless steel for improved durability and resistance to heat and corrosion.
Does this kit include gaskets?
Yes. Wehrli includes the required gaskets to ensure a proper seal between the exhaust manifolds and turbo piping.
Will this fit a stock turbo setup?
