or stealthmode for a diy log mani.

 

If you have a local industrial piping supply they normally sell els at half what mcmaster does, and do not charge shipping over and above the cost of the els. Get 304 or 304L, as the 316 tends to corrode badly over time. 304 is borderline at the heat range a manifold operated at, 316 is downright substandard. Cheap 321 ppls kthx!
