Default PP Renesis exhaust...

(for those that dont know, Renesis housings have water jacket grooves in the housings like 85 and older motors)

Its been quite hard to find a decent pair of gsl-se housings. and the prices on them are only going up. Even if your willing to pay 400 bucks for a used set of SE housings, whats the chance you'll find another quality set if you scar one...? So i been looking really close at my renesis housings and i think it is very possible to put a PP exhaust on them. I have everything figured out except for one thing... How to keep the water out. I dont think JB weld or Devcon would handle the heat down there. And i dont think a sleeve would make a water tight seal even with a machined press fit. any ideas on this?

the only idea i had was to make a sleeve from stainless and weld it to the chrome lining. This would make it so i would not have to puddy the water jacket area. but i am unsure if this would cause a problem with the heat from the exhaust.

Renesis housings can be had for much less then SE housings, and with much less miles. The chroming process is far more superior also. This could be a great alternative to using SE housings and machining water jacket grooves in 86+ housings.

any thoughts or ideas would be helpful here.
