What do they need done to them and whats the price. May know someone.

one riser needs to be rebuilt , its rusted and leaking in the center of the collector , not leaking into the exhaust side , just outside , aside from that there good , 4.5 inch tails completely dry , small bung at the tip of the pipe for cooling water , if you want pics i'll snap some for you
looking to get 500 bucks , not bad for headers / risers / tails

Enforcer24- Can you tell me how you routed your water lines? Is your exhaust wet or dry?

Scott

IT'S wet , i used a crossover system , but that really doesnt change much , water comes from the sea water pump to my crossover , thru the engine and out the thermostat housing to the bottem of the manifolds and out the exhaust , if your running a circulating pump on the engine (water pump) , the only change to your system is using 2 "T"'s to eliminate the water lines that would run to your risers , sending all the water to the bottem of the exhaust manifolds
or buying a thermostat housing that has only the 2 lines out for water to the manifolds
let me know if theres anything else i can help with

I bought 2 sets of GLM exhaust a few months back, what a joke. They went straight back. I bit the bullet and bought Stainless Marine.

I havent heard much good about the GLM's , theres no doubt that if you can afford stainless marine manifolds there the best before stepping up to true headers like CMI or Stellings , but not everyone can afford that kinda stuff

If you want GILS, I have a customer who just upgraded and has a couple sets for sale.

PM me for his info.

Stainless Marine was out of my comfort price range, until someone pointed out the ease of the dry joint riser removal. My engines are so tight in the boat, that I have to remove the inside risers and manifolds to get to anything. The fact that my life will now be so much easier was worth the extra cost. They also make custom risers to your application to prevent reversion issues should you ever want to go to a more radical cam.




A few pics of the GLM that I reccieved.....yes all 4 manifolds came in that little box.


for the reccord, I dont have an axe to grind with GLM, I just dont want to see anyone else get stuck paying very pricy return shipping becase they expected a lot higher quality.

Picture # 2 holy crap , how could they send things out looking like that ? , with the almost guarenteed water leak your gonna have at that riser fitting , wonder if there paying for many replacement engines ?

GLM= China crap
