what stock merc exhaust crap weighs... well for a sbc anyway... the tally is in...

exhaust manifold only... 47 lbs

exhaust manifold w/ riser - 68 lbs

GLM aluminum exhaust manifold only - 16 lbs

if we do some math.. since density of the materials are the only variable because and these are supposed to be damn close exact copies so the material volumes should be very close..

47/68 = 16/X --> X = 23.2 lbs for a GLM aluminum manifold & riser assembly...

therefore going to an aluminum GLM manifold and riser system should save you 90 lbs...

Well, I had to ride the "short bus" to math class, so I never got to that fancy, schmancy algebra stuff, so you'll need to tell me why it doesn' t save 104 pounds.

The weight of 2 stock manifolds and risers minus the weight of 2 aluminum manifolds should equal the weight savings............ right?? <scratch head>

(68 x 2) - (16 x 2) = 104 pounds.

Or are you talking Canadian????

What am I missing here?

Edit: OIC, you had to calculate the unknown weight of aluminum risers. Now I get it. Do I get an M&M???

Mentaly adding for S/S risers, Hmmmmm!
