In the V8 GM Small Block, GLM's fully tuned 
design guides exhaust gases directly to 
the riser without turbulance and back pressure.
This increases the engine's performance by 10%.
These GLM manifolds also feature an additional 40%
increase in water cooling area that decreases the 
manifold's overall body temperature significantly.

*All exhaust manifolds and risers are powdercoated black for maximum corrosion protection*

**Cast Iron manifolds and risers come with a 3 year warranty**
