Whether you need one replacement up-pipe bolt because it broke or you need a full set, Rudy's has you covered! We recommend installing a full set of bolts so you never have to worry about breaking a stock bolt again. These bolts secure the up-pipe to the exhaust manifold and turbo assembly, feature a black finish and have a 12 point head. These bolts are Grade 12.9 providing a substantial extra margin of safety over Grade 8 hardware. The stock bolts have tendency to break when reused, so skip the hassle and replace them when the up pipes are already out!
