GLM manifolds
Have you had success with the GLM manifolds?
I would love to hear some "good" reports after all the "Good Luck Marine" stories I've heard in my research. Or, have I just uncovered the "vocal few" that make this product look suspect.
Truly I would like to buy these as they look good and the pricing is great...but I'm not looking to do this twice (or more). I have heard about poor mating surfaces, cracks from poor casting, poor repairs made on new manifolds from the factory, non uniformity, and porosity issues in general.
Their Customer service dept. seems to be top notch in solving these isues....but there seems to be too many issues to solve in the first place.
I would appreciate hearing any experiences with the GLM manifolds/risers.
FYI - my application is a 4.3 V6 with diverters (there ain't much on the market to choose from)
