Exhaust Assembly: Grease or Paste?

Exhaust Assembly: Grease or Paste?It’s a question the SkillShack with Practical Classics team are often asked: when assembling a new exhaust, should you use an assembly paste or copper grease? Well, exhaust paste expands as it gets hot and dries out, thus guaranteeing no leaks even if the pipes are a poor fit. However, it makes the sections harder to disassemble at a later date. Copper grease makes for easy disassembly but won’t seal leaks. Decide which solution best suits your needs by trial-fitting the sections on the floor first. If they’re a snug fit, use grease.
