Whether you need one replacement up-pipe bolt because it broke or you need a full set, this Max-Flow kit 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 bolt have a tendency to break when reused, skip the hassle and replace them when the up pipes are already out.

Features:
- 12 pt head for more surface area to grip to reduce chance of stripping
- Black coating for corrosion resistance
- Grade 12.9 for additional strength

NOTE: These bolts will also fit the LB7 downpipe, you will need 4 to replace the factory bolts, there are 2 studs with that you can reuse or replace.
